 98-242 3.61e-104

first calponin homology (CH) domain found in the plastin family; The plastin family includes plastin-1, -2, and -3, which are all actin-bundling proteins. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, LC64P, or lymphocyte cytosolic protein 1 (LCP-1), plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Members of this family contain four copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

 374-507 9.22e-94

calponin homology (CH) domain superfamily; CH domains are actin filament (F-actin) binding motifs, which may be present as a single copy or in tandem repeats (which increase binding affinity). They either function as autonomous actin binding motifs or serve a regulatory function. CH domains are found in cytoskeletal and signal transduction proteins, including actin-binding proteins like spectrin, alpha-actinin, dystrophin, utrophin, and fimbrin, as well as proteins essential for regulation of cell shape (cortexillins), and signaling proteins (Vav).

CH domains are actin filament (F-actin) binding motifs.

Calponin homology (CH) domain; The CH domain is found in both cytoskeletal proteins and signal transduction proteins. The CH domain is involved in actin binding in some members of the family. However in calponins there is evidence that the CH domain is not involved in its actin binding activity. Most member proteins have from two to four copies of the CH domain, however some proteins such as calponin have only a single copy.

first calponin homology (CH) domain found in the plastin family; The plastin family includes plastin-1, -2, and -3, which are all actin-bundling proteins. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, LC64P, or lymphocyte cytosolic protein 1 (LCP-1), plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Members of this family contain four copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

third calponin homology (CH) domain found in the plastin/fimbrin family; This family includes plastin and fimbrin. Plastin has three isoforms, plastin-1, -2, and -3. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, or LC64P, or lymphocyte cytosolic protein 1 (LCP-1), is an actin-binding protein that plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28.

Plastin-3, also called T-plastin, is an actin-bundling protein found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Fimbrin has been found in plants and fungi. Arabidopsis thaliana fimbrin (AtFIM) includes fimbrin-1, -2, -3, -4, and -5, which cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Fungal fimbrin binds to actin, and functionally associates with actin structures involved in the development and maintenance of cell polarity. Members of this family contain four copies of the CH domain. This model corresponds to the third CH domain. CH domains are actin filament (F-actin) binding motifs.

 516-620 3.74e-41

fourth calponin homology (CH) domain found in the plastin/fimbrin family; This family includes plastin and fimbrin. Plastin has three isoforms, plastin-1, -2, and -3. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, or LC64P, or lymphocyte cytosolic protein 1 (LCP-1), is an actin-binding protein that plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is an actin-bundling protein found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Fimbrin has been found in plants and fungi. Arabidopsis thaliana fimbrin (AtFIM) includes fimbrin-1, -2, -3, -4, and -5, which cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Fungal fimbrin binds to actin, and functionally associates with actin structures involved in the development and maintenance of cell polarity. Members of this family contain four copies of the CH domain. This model corresponds to the fourth CH domain. CH domains are actin filament (F-actin) binding motifs.

 123-233 3.26e-16

calponin homology (CH) domain superfamily; CH domains are actin filament (F-actin) binding motifs, which may be present as a single copy or in tandem repeats (which increase binding affinity). They either function as autonomous actin binding motifs or serve a regulatory function. CH domains are found in cytoskeletal and signal transduction proteins, including actin-binding proteins like spectrin, alpha-actinin, dystrophin, utrophin, and fimbrin, as well as proteins essential for regulation of cell shape (cortexillins), and signaling proteins (Vav).

Calponin homology (CH) domain; The CH domain is found in both cytoskeletal proteins and signal transduction proteins. The CH domain is involved in actin binding in some members of the family. However in calponins there is evidence that the CH domain is not involved in its actin binding activity. Most member proteins have from two to four copies of the CH domain, however some proteins such as calponin have only a single copy.

EF-hand, calcium binding motif; A diverse superfamily of calcium sensors and calcium signal modulators; most examples in this alignment model have 2 active canonical EF hands. Ca2+ binding induces a conformational change in the EF-hand motif, leading to the activation or inactivation of target proteins. EF-hands tend to occur in pairs or higher copy numbers.

 119-233 3.20e-14

third calponin homology (CH) domain found in the plastin/fimbrin family; This family includes plastin and fimbrin. Plastin has three isoforms, plastin-1, -2, and -3. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, or LC64P, or lymphocyte cytosolic protein 1 (LCP-1), is an actin-binding protein that plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is an actin-bundling protein found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Fimbrin has been found in plants and fungi. Arabidopsis thaliana fimbrin (AtFIM) includes fimbrin-1, -2, -3, -4, and -5, which cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Fungal fimbrin binds to actin, and functionally associates with actin structures involved in the development and maintenance of cell polarity. Members of this family contain four copies of the CH domain. This model corresponds to the third CH domain. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in the beta spectrin family; The beta spectrin family includes beta-I, -II, -III, -IV and -V spectrins. Spectrin is an actin crosslinking and molecular scaffold protein that links the plasma membrane to the actin cytoskeleton, and functions in the determination of cell shape, arrangement of transmembrane proteins, and organization of organelles. It is composed of two antiparallel dimers of alpha- and beta- subunits. Beta-I spectrin, also called spectrin beta chain, erythrocytic (SPTB), may be involved in anaemia pathogenesis. Beta-II spectrin, also called spectrin beta chain, non-erythrocytic 1 (SPTBN1), or fodrin beta chain, is a component of fodrin, which is the general spectrin-like protein that seems to be involved in secretion. Fodrin interacts with calmodulin in a calcium-dependent manner and is thus a candidate for the calcium-dependent movement of the cytoskeleton at the membrane. Beta-IV spectrin is also called spectrin, non-erythroid beta chain 3 (SPTBN3) or spectrin beta chain, non-erythrocytic 4 (SPTBN4). Its mutation associates with congenital myopathy, neuropathy, and central deafness. Beta-III spectrin is also called spectrin beta chain, non-erythrocytic 2 (SPTBN2), or spinocerebellar ataxia 5 protein (SCA5). Beta-V spectrin, also called spectrin beta chain, non-erythrocytic 5 (SPTBN5), is a mammalian ortholog of Drosophila beta H spectrin. Beta-III and Beta-V spectrins may play crucial roles as longer actin-membrane cross-linkers or fulfill the need for greater extensible flexibility than can be provided by the other smaller conventional spectrins. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

third calponin homology (CH) domain found in the plastin family; The plastin family includes plastin-1, -2, and -3. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, or LC64P, or lymphocyte cytosolic protein 1 (LCP-1), is an actin-binding protein that plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is an actin-bundling protein found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Members of this family contain four copies of the CH domain. This model corresponds to the third CH domain. CH domains are actin filament (F-actin) binding motifs.

 122-232 1.03e-08

first calponin homology (CH) domain found in the beta spectrin family; The beta spectrin family includes beta-I, -II, -III, -IV and -V spectrins. Spectrin is an actin crosslinking and molecular scaffold protein that links the plasma membrane to the actin cytoskeleton, and functions in the determination of cell shape, arrangement of transmembrane proteins, and organization of organelles. It is composed of two antiparallel dimers of alpha- and beta- subunits. Beta-I spectrin, also called spectrin beta chain, erythrocytic (SPTB), may be involved in anaemia pathogenesis. Beta-II spectrin, also called spectrin beta chain, non-erythrocytic 1 (SPTBN1), or fodrin beta chain, is a component of fodrin, which is the general spectrin-like protein that seems to be involved in secretion. Fodrin interacts with calmodulin in a calcium-dependent manner and is thus a candidate for the calcium-dependent movement of the cytoskeleton at the membrane. Beta-IV spectrin is also called spectrin, non-erythroid beta chain 3 (SPTBN3) or spectrin beta chain, non-erythrocytic 4 (SPTBN4). Its mutation associates with congenital myopathy, neuropathy, and central deafness. Beta-III spectrin is also called spectrin beta chain, non-erythrocytic 2 (SPTBN2), or spinocerebellar ataxia 5 protein (SCA5). Beta-V spectrin, also called spectrin beta chain, non-erythrocytic 5 (SPTBN5), is a mammalian ortholog of Drosophila beta H spectrin. Beta-III and Beta-V spectrins may play crucial roles as longer actin-membrane cross-linkers or fulfill the need for greater extensible flexibility than can be provided by the other smaller conventional spectrins. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

 410-500 1.23e-08

first calponin homology (CH) domain found in the plastin/fimbrin family; This family includes plastin and fimbrin. Plastin has three isoforms, plastin-1, -2, and -3, which are all actin-bundling proteins. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, LC64P, or lymphocyte cytosolic protein 1 (LCP-1), plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Fimbrin has been found in plants and fungi. Arabidopsis thaliana fimbrin (AtFIM) includes fimbrin-1, -2, -3, -4, and -5; they cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Fungal fimbrin binds to actin, and functionally associates with actin structures involved in the development and maintenance of cell polarity. Members of this family contain four copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in the filamin family; The filamin family includes filamin-A (FLN-A), filamin-B (FLN-B) and filamin-C (FLN-C). Filamins function to anchor various transmembrane proteins to the actin cytoskeleton. FLN-A is also called actin-binding protein 280 (ABP-280), alpha-filamin, endothelial actin-binding protein, filamin-1, or non-muscle filamin. It promotes orthogonal branching of actin filaments and links actin filaments to membrane glycoproteins. It also serves as a scaffold for a wide range of cytoplasmic signaling proteins. FLN-B is also called ABP-278, ABP-280 homolog, actin-binding-like protein, beta-filamin, filamin homolog 1 (Fh1), filamin-3, thyroid autoantigen, truncated actin-binding protein, or truncated ABP. It connects cell membrane constituents to the actin cytoskeleton and may also promote orthogonal branching of actin filaments as well as link actin filaments to membrane glycoproteins. FLN-C, also called FLNc, ABP-280-like protein, ABP-L, actin-binding-like protein, filamin-2, or gamma-filamin, is a muscle-specific filamin that plays a central role in muscle cells, probably by functioning as a large actin-cross-linking protein. It may be involved in reorganizing the actin cytoskeleton in response to signaling events, and may also display structural functions at the Z lines in muscle cells. FLN-C is critical for normal myogenesis and for maintaining the structural integrity of the muscle fibers. This family also includes Drosophila melanogaster protein jitterbug (Jbug), which is an actin-meshwork organizing protein containing three copies of the CH domain. Other members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in filamin-C (FLN-C) and similar proteins; Filamin-C (FLN-C), also called FLNc, ABP-280-like protein, ABP-L, actin-binding-like protein, filamin-2, or gamma-filamin, is a muscle-specific filamin that plays a central role in muscle cells, probably by functioning as a large actin-cross-linking protein. It may be involved in reorganizing the actin cytoskeleton in response to signaling events, and may also display structural functions at the Z lines in muscle cells. FLN-C is critical for normal myogenesis and for maintaining the structural integrity of the muscle fibers. FLN-C contains two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

 389-501 3.63e-08

first calponin homology (CH) domain found in spectrin beta chain, non-erythrocytic 1 (SPTBN1) and similar proteins; Spectrin is an actin crosslinking and molecular scaffold protein that links the plasma membrane to the actin cytoskeleton, and functions in the determination of cell shape, arrangement of transmembrane proteins, and organization of organelles. It is composed of two antiparallel dimers of alpha- and beta- subunits. SPTBN1, also called beta-II spectrin, fodrin beta chain, or spectrin, non-erythroid beta chain 1, is also a component of fodrin, which is the general spectrin-like protein that seems to be involved in secretion. Fodrin interacts with calmodulin in a calcium-dependent manner and is thus a candidate for the calcium-dependent movement of the cytoskeleton at the membrane. SPTBN1 contains two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in the plectin/dystonin/MACF1 family; This family includes plectin, dystonin and microtubule-actin cross-linking factor 1, isoforms 1/2/3/5 (MACF1). Plectin, also called PCN, PLTN, hemidesmosomal protein 1 (HD1), or plectin-1, is a structural component of muscle. It interlinks intermediate filaments with microtubules and microfilaments, and anchors intermediate filaments to desmosomes or hemidesmosomes. It could also bind muscle proteins such as actin to membrane complexes in muscle. Dystonin, also called 230 kDa bullous pemphigoid antigen, 230/240 kDa bullous pemphigoid antigen, bullous pemphigoid antigen 1 (BPA or BPAG1), dystonia musculorum protein, or hemidesmosomal plaque protein, is a cytoskeletal linker protein that acts as an integrator of intermediate filaments, actin, and microtubule cytoskeleton networks. It is required for anchoring either intermediate filaments to the actin cytoskeleton in neural and muscle cells, or keratin-containing intermediate filaments to hemidesmosomes in epithelial cells. MACF1, also called 620 kDa actin-binding protein (ABP620), actin cross-linking family protein 7 (ACF7), macrophin-1, or trabeculin-alpha, is a large protein containing numerous spectrin and leucine-rich repeat (LRR) domains. It facilitates actin-microtubule interactions at the cell periphery and couples the microtubule network to cellular junctions. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in the synaptic nuclear envelope protein family; The synaptic nuclear envelope (SYNE) family includes SYNE-1, -2 and calmin. SYNE-1 (also called nesprin-1, enaptin, KASH domain-containing protein 1, KASH1, myocyte nuclear envelope protein 1, MYNE-1, or nuclear envelope spectrin repeat protein 1) and SYNE-2 (also called nesprin-2, KASH domain-containing protein 2, KASH2, nuclear envelope spectrin repeat protein 2, nucleus and actin connecting element protein, or protein NUANCE) may act redundantly. They are multi-isomeric modular proteins which form a linking network between organelles and the actin cytoskeleton to maintain subcellular spatial organization. They also act as components of the LINC (LInker of Nucleoskeleton and Cytoskeleton) complex, which is involved in the connection between the nuclear lamina and the cytoskeleton. Calmin, also called calponin-like transmembrane domain protein, is a protein with calponin homology (CH) and transmembrane domains expressed in maturing spermatogenic cells. It may be involved in the development and/or maintenance of neuronal functions. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

 396-499 4.05e-07

first calponin homology (CH) domain found in utrophin and similar proteins; Utrophin, also called dystrophin-related protein 1 (DRP-1), is an autosomal dystrophin homolog that increases dystrophic muscle function and reduces pathology. It is broadly expressed in both the mRNA and protein levels, and occurs in the cerebrovascular endothelium. Utrophin forms the utrophin-glycoprotein complex (UGC) by interacting with dystroglycans (DGs) and sarcoglycan-dystroglycans, as well as sarcoglycan and sarcospan (SG-SSPN) subcomplexes. It may act as a scaffolding protein that stabilizes lipid microdomains and clusters mechanosensitive channel subunits, and link the F-actin cytoskeleton to the cell membrane via the associated glycoprotein complex. Like dystrophin, utrophin has a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. These domains are believed to be involved in protein-protein interactions. In addition, it contains two syntrophin binding sites (SBSs) and a long N-terminal extension that comprises two actin-binding calponin homology (CH) domains, up to 24 spectrin repeats (SRs), and a WW domain. However, utrophin lacks the intrinsic microtubule binding activity of dystrophin SRs. This model corresponds to the first CH domain.

first calponin homology (CH) domain found in filamins; The filamin family includes filamin-A (FLN-A), filamin-B (FLN-B) and filamin-C (FLN-C). Filamins function to anchor various transmembrane proteins to the actin cytoskeleton. FLN-A is also called actin-binding protein 280 (ABP-280), alpha-filamin, endothelial actin-binding protein, filamin-1, or non-muscle filamin. It promotes orthogonal branching of actin filaments and links actin filaments to membrane glycoproteins. It also serves as a scaffold for a wide range of cytoplasmic signaling proteins. FLN-B is also called ABP-278, ABP-280 homolog, actin-binding-like protein, beta-filamin, filamin homolog 1 (Fh1), filamin-3, thyroid autoantigen, truncated actin-binding protein, or truncated ABP. It connects cell membrane constituents to the actin cytoskeleton and may also promote orthogonal branching of actin filaments as well as link actin filaments to membrane glycoproteins. FLN-C, also called FLNc, ABP-280-like protein, ABP-L, actin-binding-like protein, filamin-2, or gamma-filamin, is a muscle-specific filamin that plays a central role in muscle cells, probably by functioning as a large actin-cross-linking protein. It may be involved in reorganizing the actin cytoskeleton in response to signaling events, and may also display structural functions at the Z lines in muscle cells. FLN-C is critical for normal myogenesis and for maintaining the structural integrity of the muscle fibers. Members of this family contain two copies of the CH domain. The model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

 16-77 1.30e-06

EF-hand, calcium binding motif, found in the hexa-EF hand proteins family; The hexa-EF hand proteins family, also named the calbindin sub-family, contains a group of six EF-hand Ca2+-binding proteins, including calretinin (CR, also termed 29 kDa calbindin), calbindin D28K (CB, also termed vitamin D-dependent calcium-binding protein, avian-type), and secretagogin (SCGN). CR is a cytosolic hexa-EF-hand calcium-binding protein predominantly expressed in a variety of normal and tumorigenic t-specific neurons of the central and peripheral nervous system. It is a multifunctional protein implicated in many biological processes, including cell proliferation, differentiation, and cell death. CB is highly expressed in brain tissue. It is a strong calcium-binding and buffering protein responsible for preventing a neuronal death as well as maintaining and controlling calcium homeostasis. SCGN is a six EF-hand calcium-binding protein expressed in neuroendocrine, pancreatic endocrine and retinal cells. It plays a crucial role in cell apoptosis, receptor signaling and differentiation. It is also involved in vesicle secretion through binding to various proteins, including interacts with SNAP25, SNAP23, DOC2alpha, ARFGAP2, rootletin, KIF5B, beta-tubulin, DDAH-2, ATP-synthase and myeloid leukemia factor 2. SCGN functions as a Ca2+ sensor/coincidence detector modulating vesicular exocytosis of neurotransmitters, neuropeptides or hormones. Although the family members share a significant amount of secondary sequence homology, they display altered structural and biochemical characteristics, and operate in distinct fashions. CB contains six EF-hand motifs in a single globular domain, where EF-hands 1, 3, 4, 5 bind four calcium ions. CR contains six EF-hand motifs within two independent domains, CR I-II and CR III-VI. They harbor two and four EF-hand motifs, respectively. The first 5 EF-hand motifs are capable of binding calcium ions, while the EF-hand 6 is inactive. SCGN consists of the three globular domains each of which contains a pair of EF-hand motifs. Human SCGN simultaneously binds four calcium ions through its EF-hands 3, 4, 5 and 6 in one high affinity and three low affinity calcium-binding sites. In contrast, SCGNs in other lower eukaryotes, such as D. rerio, X. laevis, M. domestica, G. gallus, O. anatinus, are fully competent in terms of six calcium-binding.

 396-496 2.44e-06

first calponin homology (CH) domain found in the dystrophin family; The dystrophin family includes dystrophin and its paralog, utrophin. Dystrophin, encoded by the DMD gene, is a large, submembrane cytoskeletal protein that is the main component of the dystrophin-glycoprotein complex (DGC) in skeletal muscles. It links the transmembrane DGC to the actin cytoskeleton through binding strongly to the cytoplasmic tail of beta-dystroglycan, the transmembrane subunit of a highly O-glycosylated cell-surface protein. Dystrophin is also involved in maintaining the structural integrity of cells, as well as in the formation of the blood-brain barrier (BBB). Utrophin, also called dystrophin-related protein 1 (DRP-1), is an autosomal dystrophin homolog that increases dystrophic muscle function and reduces pathology. It is broadly expressed in both the mRNA and protein levels, and occurs in the cerebrovascular endothelium. Utrophin forms the utrophin-glycoprotein complex (UGC) by interacting with dystroglycans (DGs) and sarcoglycan-dystroglycans, as well as sarcoglycan and sarcospan (SG-SSPN) subcomplexes. It may act as a scaffolding protein that stabilizes lipid microdomains and clusters mechanosensitive channel subunits, and links the F-actin cytoskeleton to the cell membrane via the associated glycoprotein complex. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

third calponin homology (CH) domain found in the Arabidopsis thaliana fimbrin family; The Arabidopsis thaliana fimbrin (AtFIM) family includes Fimbrin-1, -2, -3, -4, and -5, which cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Members of this family contain four copies of the CH domain. This model corresponds to the third CH domain. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in the alpha-actinin family; The alpha-actinin (ACTN) family includes alpha-actinin-1, -2, -3, and -4. They are F-actin cross-linking proteins which are thought to anchor actin to a variety of intracellular structures. ACTN1 mutations cause congenital macrothrombocytopenia. ACTN2 mutations are associated with cardiomyopathies, as well as skeletal muscle disorder. ACTN3 is critical in anchoring the myofibrillar actin filaments and plays a key role in muscle contraction. ACTN4 is associated with cell motility and cancer invasion. It is probably involved in vesicular trafficking via its association with the CART complex, which is necessary for efficient transferrin receptor recycling but not for epidermal growth factor receptor (EGFR) degradation. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

It links the transmembrane DGC to the actin cytoskeleton through binding strongly to the cytoplasmic tail of beta-dystroglycan, the transmembrane subunit of a highly O-glycosylated cell-surface protein. It is involved in maintaining the structural integrity of cells, as well as in the formation of the blood-brain barrier (BBB). Mutations in dystrophin lead to Duchenne muscular dystrophy (DMD). Moreover, dystrophin deficiency is associated with abnormal cerebral diffusion and perfusion, as well as in acute Trypanosoma cruzi infection. The dystrophin subfamily has been characterized by a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. These domains are believed to be involved in protein-protein interactions. In addition, dystrophin contains two syntrophin binding sites (SBSs) and a long N-terminal extension that comprises two actin-binding calponin homology (CH) domains, approximately 24 spectrin repeats (SRs) and a WW domain. This model corresponds to the first CH domain.

 13-74 2.82e-06

EF-hand, calcium binding motif, found in parvalbumin-like EF-hand family; The family includes alpha- and beta-parvalbumins, and a group of uncharacterized calglandulin-like proteins. Parvalbumins are small, acidic, cytosolic EF-hand-containing Ca2+-buffer and Ca2+ transporter/shuttle proteins belonging to EF-hand superfamily. They are expressed by vertebrates in fast-twitch muscle cells, specific neurons of the central and peripheral nervous system, sensory cells of the mammalian auditory organ (Corti's cell), and some other cells, and characterized by the presence of three consecutive EF-hand motifs (helix-loop-helix) called AB, CD, and EF, but only CD and EF can chelate metal ions, such as Ca2+ and Mg2+. Thus, they may play an additional role in Mg2+ handling. Moreover, parvalbumins represent one of the major animal allergens. In metal-bound states, parvalbumins possess a rigid and stable tertiary structure and display strong allergenicity. In contrast, the metal-free parvalbumins are intrinsically disordered, and the loss of metal ions results in a conformational change that decreases their IgE binding capacity. Furthermore, parvalbumins have been widely used as a neuronal marker for a variety of functional brain systems. They also function as a Ca2+ shuttle transporting Ca2+ from troponin-C (TnC) to the sarcoplasmic reticulum (SR) Ca2+ pump during muscle relaxation. Thus they may facilitate myocardial relaxation and play important roles in cardiac diastolic dysfunction. Parvalbumins consists of alpha- and beta- sublineages, which can be distinguished on the basis of isoelectric point (pI > 5 for alpha; pI

 13-74 3.51e-06

EF-hand, calcium binding motif, found in homologs of mammalian apoptosis-linked gene 2 protein (ALG-2); The family includes some homologs of mammalian apoptosis-linked gene 2 protein (ALG-2) mainly found in lower eukaryotes, such as a parasitic protist Leishmarua major and a cellular slime mold Dictyostelium discoideum. These homologs contains five EF-hand motifs. Due to the presence of unfavorable residues at the Ca2+-coordinating positions, their non-canonical EF4 and EF5 hands may not bind Ca2+. Two Dictyostelium PEF proteins are the prototypes of this family. They may bind to cytoskeletal proteins and/or signal-transducing proteins localized to detergent-resistant membranes named lipid rafts, and occur as monomers or weak homo- or heterodimers like ALG-2. They can serve as a mediator for Ca2+ signaling-related Dictyostehum programmed cell death (PCD).

EF-hand motif found in eukaryotic phosphoinositide-specific phospholipase C (PI-PLC, EC 3.1.4. ...
 14-94 4.41e-06

EF-hand motif found in eukaryotic phosphoinositide-specific phospholipase C (PI-PLC, EC 3.1.4.11) isozymes; PI-PLC isozymes are signaling enzymes that hydrolyze the membrane phospholipids phosphatidylinositol-4,5-bisphosphate (PIP2) to generate two important second messengers in eukaryotic signal transduction cascades, Inositol 1,4,5-trisphosphate (InsP3) and diacylglycerol (DAG). InsP3 triggers inflow of calcium from intracellular stores, while DAG, together with calcium, activates protein kinase C, which goes on to phosphorylate other molecules, leading to altered cellular activity. Calcium is required for the catalysis. This family corresponds to the four EF-hand motifs containing PI-PLC isozymes, including PI-PLC-beta (1-4), -gamma (1-2), -delta (1,3,4), -epsilon (1), -zeta (1), eta (1-2). Lower eukaryotes such as yeast and slime molds contain only delta-type isozymes. In contrast, other types of isoforms present in higher eukaryotes. This family also includes 1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase 1 (PLC1) from fungi. Some homologs from plants contain only two atypical EF-hand motifs and they are not included. All PI-PLC isozymes except sperm-specific PI-PLC-zeta share a core set of domains, including an N-terminal pleckstrin homology (PH) domain, four atypical EF-hand motifs, a PLC catalytic core, and a single C2 domain. PI-PLC-zeta lacks the PH domain. The PLC catalytic core domain is a TIM barrel with two highly conserved regions (X and Y) split by a highly degenerate linker sequence. Most of EF-hand motifs found in PI-PLCs consist of a helix-loop-helix structure, but lack residues critical to metal binding. Moreover, the EF-hand region of most of PI-PLCs may have an important regulatory function, but it has yet to be identified. However, PI-PLC-zeta is a key exception. It is responsible for Ca2+ oscillations in fertilized oocytes and exhibits a high sensitivity to Ca2+ mediated through its EF-hand domain. In addition, PI-PLC-eta2 shows a canonical EF-loop directing Ca2+-sensitivity and thus can amplify transient Ca2+ signals. Also it appears that PI-PLC-delta1 can regulate the binding of PH domain to PIP2 in a Ca2+-dependent manner through its functionally important EF-hand domains. PI-PLCs can be activated by a variety of extracellular ligands, such as growth factors, hormones, cytokines and lipids. Their activation has been implicated in tumorigenesis and/or metastasis linked to migration, proliferation, growth, inflammation, angiogenesis and actin cytoskeleton reorganization. PI-PLC-beta isozymes are activated by G-protein coupled receptor (GPCR) through different mechanisms. However, PI-PLC-gamma isozymes are activated by receptor tyrosine kinase (RTK), such as Rho and Ras GTPases. In contrast, PI-PLC-epsilon are activated by both GPCR and RTK. PI-PLC-delta1 and PLC-eta 1 are activated by GPCR-mediated calcium mobilization. The activation mechanism for PI-PLC-zeta remains unclear.

 122-232 9.23e-06

first calponin homology (CH) domain found in the beta-I spectrin-like subfamily; The beta-I spectrin-like family includes beta-I, -II, -III and -IV spectrins. Spectrin is an actin crosslinking and molecular scaffold protein that links the plasma membrane to the actin cytoskeleton, and functions in the determination of cell shape, arrangement of transmembrane proteins, and organization of organelles. It is composed of two antiparallel dimers of alpha- and beta- subunits. Beta-I spectrin, also called spectrin beta chain, erythrocytic (SPTB), may be involved in anaemia pathogenesis. Beta-II spectrin, also called spectrin beta chain, non-erythrocytic 1 (SPTBN1), or fodrin beta chain, is a component of fodrin, which is the general spectrin-like protein that seems to be involved in secretion. Fodrin interacts with calmodulin in a calcium-dependent manner and is thus a candidate for the calcium-dependent movement of the cytoskeleton at the membrane. Beta-III spectrin, also called spectrin beta chain, non-erythrocytic 2 (SPTBN2), or spinocerebellar ataxia 5 protein (SCA5), may play a crucial role as a longer actin-membrane cross-linker or fulfill the need for greater extensible flexibility than can be provided by the other smaller conventional spectrins. Beta-IV spectrin is also called spectrin, non-erythroid beta chain 3 (SPTBN3) or spectrin beta chain, non-erythrocytic 4 (SPTBN4). Its mutation associates with congenital myopathy, neuropathy, and central deafness. Members of this subfamily contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

 13-79 1.08e-05

EF-hand, calcium binding motif, found in alpha-parvalbumin; Alpha-parvalbumin is cytosolic Ca2+/Mg2+-binding protein expressed mainly in fast-twitch skeletal myofibrils, where it may act as a soluble relaxing factor facilitating the Ca2+-mediated relaxation phase. It is also expressed in rapidly firing neurons, particularly GABA-ergic neurons, and thus may confer protection against Ca2+ toxicity. The major role of alpha-parvalbumin is metal buffering and transport of Ca2+. It binds different metal cations, and exhibits very high affinity for Ca2+ and physiologically significant affinity for Mg2+. Alpha-parvalbumin is characterized by the presence of three consecutive EF-hand motifs (helix-loop-helix) called AB, CD, and EF, but only CD and EF can chelate metal ions, such as Ca2+ and Mg2+. Both metal ion-binding sites in alpha-parvalbumin are high-affinity sites. Additionally, in contrast to beta-parvalbumin, alpha-parvalbumin is less acidic and has an additional residue in the C-terminal helix.

EF hand; The EF-hands can be divided into two classes: signalling proteins and buffering/transport proteins. The first group is the largest and includes the most well-known members of the family such as calmodulin, troponin C and S100B. These proteins typically undergo a calcium-dependent conformational change which opens a target binding site. The latter group is represented by calbindin D9k and do not undergo calcium dependent conformational changes.

EF-hand, calcium binding motif, found in uncharacterized calglandulin-like proteins; The family corresponds to a group of uncharacterized calglandulin-like proteins. Although their biological function remain unclear, they show high sequence similarity with human calglandulin-like protein GAGLP, which is an ortholog of calglandulin from the venom glands of Bothrops insularis snake. Both GAGLP and calglandulin are putative Ca2+-binding proteins with four EF-hand motifs. However, members in this family contain only three EF-hand motifs. In this point, they may belong to the parvalbumin-like EF-hand family, which is characterized by the presence of three consecutive EF-hand motifs (helix-loop-helix).

 518-613 1.25e-05

second calponin homology (CH) domain found in the plastin/fimbrin family; This family includes plastin and fimbrin. Plastin has three isoforms, plastin-1, -2, and -3, which are all actin-bundling proteins. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, LC64P, or lymphocyte cytosolic protein 1 (LCP-1), plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Fimbrin has been found in plants and fungi. Arabidopsis thaliana fimbrin (AtFIM) includes fimbrin-1, -2, -3, -4, and -5; they cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Fungal fimbrin binds to actin, and functionally associates with actin structures involved in the development and maintenance of cell polarity. Members of this family contain four copies of the CH domain. This model corresponds to the second CH domain. CH domains are actin filament (F-actin) binding motifs.

 15-92 1.73e-05

Penta-EF hand, calcium binding motifs, found in Group I PEF proteins; The family corresponds to Group I PEF proteins that have been found not only in higher animals but also in lower animals, plants, fungi and protists. Group I PEF proteins include apoptosis-linked gene 2 protein (ALG-2), peflin and similar proteins. ALG-2, also termed programmed cell death protein 6 (PDCD6), is a widely expressed calcium-binding modulator protein associated with cell proliferation and death, as well as cell survival. It forms a homodimer in the cell or a heterodimer with its closest paralog peflin. Among the PEF proteins, ALG-2 can bind three Ca2+ ions through its EF1, EF3, and EF5 hands, where it is unique in that its EF5 hand binds Ca2+ ion in a canonical coordination. Peflin is a ubiquitously expressed 30-kD PEF protein containing five EF-hand motifs in its C-terminal domain and a longer N-terminal hydrophobic domain (NHB domain) than any other member of the PEF family. The NHB domain harbors nine repeats of a nonapeptide (A/PPGGPYGGP). Peflin may modulate the function of ALG-2 in Ca2+ signaling. It exists only as a heterodimer with ALG-2, and binds two Ca2+ ions through its EF1 and EF3 hands. Its additional EF5 hand is unpaired and does not bind Ca2+ ion but mediates the heterodimerization with ALG-2. The dissociation of heterodimer occurs in the presence of Ca2+.

 13-74 1.85e-05

EF-hand, calcium binding motif, found in parvalbumins; Parvalbumins are small, acidic, cytosolic EF-hand-containing Ca2+-buffer and Ca2+ transporter/shuttle proteins belonging to EF-hand superfamily. They are expressed by vertebrates in fast-twitch muscle cells, specific neurons of the central and peripheral nervous system, sensory cells of the mammalian auditory organ (Corti's cell), and some other cells, and characterized by the presence of three consecutive EF-hand motifs (helix-loop-helix) called AB, CD, and EF, but only CD and EF can chelate metal ions, such as Ca2+ and Mg2+. Thus, they may play an additional role in Mg2+ handling. Moreover, parvalbumins represent one of the major animal allergens. In metal-bound states, parvalbumins possess a rigid and stable tertiary structure and display strong allergenicity. In contrast, the metal-free parvalbumins are intrinsically disordered, and the loss of metal ions results in a conformational change that decreases their IgE binding capacity. Furthermore, parvalbumins have been widely used as a neuronal marker for a variety of functional brain systems. They also function as a Ca2+ shuttle transporting Ca2+ from troponin-C (TnC) to the sarcoplasmic reticulum (SR) Ca2+ pump during muscle relaxation. Thus they may facilitate myocardial relaxation and play important roles in cardiac diastolic dysfunction. Parvalbumins consists of alpha- and beta- sublineages, which can be distinguished on the basis of isoelectric point (pI > 5 for alpha; pI

first calponin homology (CH) domain found in the plastin family; The plastin family includes plastin-1, -2, and -3, which are all actin-bundling proteins. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, LC64P, or lymphocyte cytosolic protein 1 (LCP-1), plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Members of this family contain four copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

 7-77 5.40e-05

EF-hand, calcium binding motif, found in the hexa-EF hand proteins family; The hexa-EF hand proteins family, also named the calbindin sub-family, contains a group of six EF-hand Ca2+-binding proteins, including calretinin (CR, also termed 29 kDa calbindin), calbindin D28K (CB, also termed vitamin D-dependent calcium-binding protein, avian-type), and secretagogin (SCGN). CR is a cytosolic hexa-EF-hand calcium-binding protein predominantly expressed in a variety of normal and tumorigenic t-specific neurons of the central and peripheral nervous system. It is a multifunctional protein implicated in many biological processes, including cell proliferation, differentiation, and cell death. CB is highly expressed in brain tissue. It is a strong calcium-binding and buffering protein responsible for preventing a neuronal death as well as maintaining and controlling calcium homeostasis. SCGN is a six EF-hand calcium-binding protein expressed in neuroendocrine, pancreatic endocrine and retinal cells. It plays a crucial role in cell apoptosis, receptor signaling and differentiation. It is also involved in vesicle secretion through binding to various proteins, including interacts with SNAP25, SNAP23, DOC2alpha, ARFGAP2, rootletin, KIF5B, beta-tubulin, DDAH-2, ATP-synthase and myeloid leukemia factor 2. SCGN functions as a Ca2+ sensor/coincidence detector modulating vesicular exocytosis of neurotransmitters, neuropeptides or hormones. Although the family members share a significant amount of secondary sequence homology, they display altered structural and biochemical characteristics, and operate in distinct fashions. CB contains six EF-hand motifs in a single globular domain, where EF-hands 1, 3, 4, 5 bind four calcium ions. CR contains six EF-hand motifs within two independent domains, CR I-II and CR III-VI. They harbor two and four EF-hand motifs, respectively. The first 5 EF-hand motifs are capable of binding calcium ions, while the EF-hand 6 is inactive. SCGN consists of the three globular domains each of which contains a pair of EF-hand motifs. Human SCGN simultaneously binds four calcium ions through its EF-hands 3, 4, 5 and 6 in one high affinity and three low affinity calcium-binding sites. In contrast, SCGNs in other lower eukaryotes, such as D. rerio, X. laevis, M. domestica, G. gallus, O. anatinus, are fully competent in terms of six calcium-binding.

 13-79 5.99e-05

EF-hand, calcium binding motif, found in beta-parvalbumin; Beta-parvalbumin, also termed Oncomodulin-1 (OM), is a small calcium-binding protein that is expressed in hepatomas, as well as in the blastocyst and the cytotrophoblasts of the placenta. It is also found to be expressed in the cochlear outer hair cells of the organ of Corti and frequently expressed in neoplasms. Mammalian beta-parvalbumin is secreted by activated macrophages and neutrophils. It may function as a tissue-specific Ca2+-dependent regulatory protein, and may also serve as a specialized cytosolic Ca2+ buffer. Beta-parvalbumin acts as a potent growth-promoting signal between the innate immune system and neurons in vivo. It has high and specific affinity for its receptor on retinal ganglion cells (RGC) and functions as the principal mediator of optic nerve regeneration. It exerts its effects in a cyclic adenosine monophosphate (cAMP)-dependent manner and can further elevate intracellular cAMP levels. Moreover, beta-parvalbumin is associated with efferent function and outer hair cell electromotility, and can identify different hair cell types in the mammalian inner ear. Beta-parvalbumin is characterized by the presence of three consecutive EF-hand motifs (helix-loop-helix) called AB, CD, and EF, but only CD and EF can chelate metal ions, such as Ca2+ and Mg2+. The EF site displays a high-affinity for Ca2+/Mg2+, and the CD site is a low-affinity Ca2+-specific site. In addition, beta-parvalbumin is distinguished from other parvalbumins by its unusually low isoelectric point (pI = 3.1) and sequence eccentricities (e.g., Y57-L58-D59 instead of F57-I58-E59).

 14-93 7.13e-05

EF-hand motif found in phosphoinositide phospholipase C delta (PI-PLC-delta); PI-PLC-delta isozymes represent a class of metazoan PI-PLCs that are some of the most sensitive to calcium among all PLCs. Their activation is modulated by intracellular calcium ion concentration, phospholipids, polyamines, and other proteins, such as RhoAGAP. Like other PI-PLC isozymes, PI-PLC-delta isozymes contain a core set of domains, including an N-terminal pleckstrin homology (PH) domain, four atypical EF-hand motifs, a PLC catalytic core, and a single C-terminal C2 domain. The PLC catalytic core domain is a TIM barrel with two highly conserved regions (X and Y) split by a highly degenerate linker sequence. There are three PI-PLC-delta isozymes (1, 3 and 4). PI-PLC-delta1 is relatively well characterized. It is activated by high calcium levels generated by other PI-PLC family members, and therefore functions as a calcium amplifier within the cell. Different PI-PLC-delta isozymes have different tissue distribution and different subcellular locations. PI-PLC-delta1 is mostly a cytoplasmic protein, PI-PLC-delta3 is located in the membrane, and PI-PLC-delta4 is predominantly detected in the cell nucleus. PI-PLC-delta isozymes is evolutionarily conserved even in non-mammalian species, such as yeast, slime molds and plants.

first calponin homology (CH) domain found in synaptic nuclear envelope protein 1 and similar proteins; Synaptic nuclear envelope protein 1 (SYNE-1), also called nesprin-1, enaptin, KASH domain-containing protein 1 (KASH1), myocyte nuclear envelope protein 1 (MYNE-1), or nuclear envelope spectrin repeat protein 1, is a multi-isomeric modular protein which forms a linking network between organelles and the actin cytoskeleton to maintain subcellular spatial organization. SYNE-1 also acts as a component of the LINC (LInker of Nucleoskeleton and Cytoskeleton) complex, which is involved in the connection between the nuclear lamina and the cytoskeleton. SYNE-1 contains two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in the alpha-actinin family; The alpha-actinin (ACTN) family includes alpha-actinin-1, -2, -3, and -4. They are F-actin cross-linking proteins which are thought to anchor actin to a variety of intracellular structures. ACTN1 mutations cause congenital macrothrombocytopenia. ACTN2 mutations are associated with cardiomyopathies, as well as skeletal muscle disorder. ACTN3 is critical in anchoring the myofibrillar actin filaments and plays a key role in muscle contraction. ACTN4 is associated with cell motility and cancer invasion. It is probably involved in vesicular trafficking via its association with the CART complex, which is necessary for efficient transferrin receptor recycling but not for epidermal growth factor receptor (EGFR) degradation. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

 7-98 1.38e-04

EF-hand, calcium binding motif, found in calumenin, reticulocalbin-1 (RCN-1), reticulocalbin-3 (RCN-3), and similar proteins; The family corresponds to a group of six EF-hand Ca2+-binding proteins, including calumenin (also known as crocalbin or CBP-50), reticulocalbin-1 (RCN-1), reticulocalbin-3 (RCN-3), and similar proteins. Calumenin is an endo/sarcoplasmic reticulum (ER/SR) resident low-affinity Ca2+-binding protein that contains six EF-hand domains and a C-terminal SR retention signal His-Asp-Glu-Phe (HDEF) tetrapeptide. It functions as a novel regulator of SERCA2, and its expressional changes are tightly coupled with Ca2+-cycling of cardiomyocytes. It is also broadly involved in haemostasis and in the pathophysiology of thrombosis. Moreover, the extracellular calumenin acts as a suppressor of cell migration and tumor metastasis. RCN-1 is an endoplasmic reticulum resident Ca2+-binding protein with a carboxyl-terminal His-Asp-Glu-Leu (HDEL) tetrapeptide signal. It acts as a potential negative regulator of B-RAF activation and can negatively modulate cardiomyocyte hypertrophy by inhibition of the mitogen-activated protein kinase signalling cascade. It also plays a key role in the development of doxorubicin-associated resistance. RCN-3 is a putative six EF-hand Ca2+-binding protein that contains five RXXR (X is any amino acid) motifs and a C-terminal ER retrieval signal HDEL tetrapeptide. The RXXR motif represents the target sequence of subtilisin-like proprotein convertases (SPCs). RCN-3 is specifically bound to the paired basic amino-acid-cleaving enzyme-4 (PACE4) precursor protein and plays an important role in the biosynthesis of PACE4.

 267-371 1.60e-04

fourth calponin homology (CH) domain found in the plastin/fimbrin family; This family includes plastin and fimbrin. Plastin has three isoforms, plastin-1, -2, and -3. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, or LC64P, or lymphocyte cytosolic protein 1 (LCP-1), is an actin-binding protein that plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is an actin-bundling protein found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Fimbrin has been found in plants and fungi. Arabidopsis thaliana fimbrin (AtFIM) includes fimbrin-1, -2, -3, -4, and -5, which cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Fungal fimbrin binds to actin, and functionally associates with actin structures involved in the development and maintenance of cell polarity. Members of this family contain four copies of the CH domain. This model corresponds to the fourth CH domain. CH domains are actin filament (F-actin) binding motifs.

 122-232 1.63e-04

first calponin homology (CH) domain found in the dystrophin family; The dystrophin family includes dystrophin and its paralog, utrophin. Dystrophin, encoded by the DMD gene, is a large, submembrane cytoskeletal protein that is the main component of the dystrophin-glycoprotein complex (DGC) in skeletal muscles. It links the transmembrane DGC to the actin cytoskeleton through binding strongly to the cytoplasmic tail of beta-dystroglycan, the transmembrane subunit of a highly O-glycosylated cell-surface protein. Dystrophin is also involved in maintaining the structural integrity of cells, as well as in the formation of the blood-brain barrier (BBB). Utrophin, also called dystrophin-related protein 1 (DRP-1), is an autosomal dystrophin homolog that increases dystrophic muscle function and reduces pathology. It is broadly expressed in both the mRNA and protein levels, and occurs in the cerebrovascular endothelium. Utrophin forms the utrophin-glycoprotein complex (UGC) by interacting with dystroglycans (DGs) and sarcoglycan-dystroglycans, as well as sarcoglycan and sarcospan (SG-SSPN) subcomplexes. It may act as a scaffolding protein that stabilizes lipid microdomains and clusters mechanosensitive channel subunits, and links the F-actin cytoskeleton to the cell membrane via the associated glycoprotein complex. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

second calponin homology (CH) domain found in the filamin family; The filamin family includes filamin-A (FLN-A), filamin-B (FLN-B) and filamin-C (FLN-C). Filamins function to anchor various transmembrane proteins to the actin cytoskeleton. FLN-A is also called actin-binding protein 280 (ABP-280), alpha-filamin, endothelial actin-binding protein, filamin-1, or non-muscle filamin. It promotes orthogonal branching of actin filaments and links actin filaments to membrane glycoproteins. It also serves as a scaffold for a wide range of cytoplasmic signaling proteins. FLN-B is also called ABP-278, ABP-280 homolog, actin-binding-like protein, beta-filamin, filamin homolog 1 (Fh1), filamin-3, thyroid autoantigen, truncated actin-binding protein, or truncated ABP. It connects cell membrane constituents to the actin cytoskeleton and may also promote orthogonal branching of actin filaments as well as link actin filaments to membrane glycoproteins. FLN-C, also called FLNc, ABP-280-like protein, ABP-L, actin-binding-like protein, filamin-2, or gamma-filamin, is a muscle-specific filamin that plays a central role in muscle cells, probably by functioning as a large actin-cross-linking protein. It may be involved in reorganizing the actin cytoskeleton in response to signaling events, and may also display structural functions at the Z lines in muscle cells. FLN-C is critical for normal myogenesis and for maintaining the structural integrity of the muscle fibers. This family also includes Drosophila melanogaster protein jitterbug (Jbug), which is an actin-meshwork organizing protein containing three copies of the CH domain. Other members of this family contain two copies of the CH domain. This model corresponds to the second CH domain. CH domains are actin filament (F-actin) binding motifs.

 15-78 2.97e-04

The penta-EF hand (PEF) family; The penta-EF hand (PEF) family contains a group of five EF-hand calcium-binding proteins, including several classical calpain large catalytic subunits (CAPN1, 2, 3, 8, 9, 11, 12, 13, 14), two calpain small subunits (CAPNS1 and CAPNS2), as well as non-calpain PEF proteins, ALG-2 (apoptosis-linked gene 2, also termed programmed cell death protein 6, PDCD6), peflin, sorcin, and grancalcin. Based on the sequence similarity of EF1 hand, ALG-2 and peflin have been classified into group I PEF proteins. Calcium-dependent protease calpain subfamily members, sorcin and grancalcin, are group II PEF proteins. Calpains (EC 3.4.22.17) are calcium-activated intracellular cysteine proteases that play important roles in the degradation or functional modulation in a variety of substrates. They have been implicated in a number of physiological processes such as cell cycle progression, remodeling of cytoskeletal-cell membrane attachments, signal transduction, gene expression and apoptosis. ALG-2 is a pro-apoptotic factor that forms a homodimer in the cell or a heterodimer with its closest paralog peflin through their EF5s. Peflin is a 30-kD PEF protein with a longer N-terminal hydrophobic domain than any other member of the PEF family, and it contains nine nonapeptide (A/PPGGPYGGP) repeats. It exists only as a heterodimer with ALG-2. The dissociation of heterodimer occurs in the presence of Ca2+. ALG-2 interacts with various proteins in a Ca2+-dependent manner. Sorcin (for soluble resistance-related calcium binding protein) is a soluble resistance-related calcium-binding protein that participates in the regulation of calcium homeostasis in cells. Grancalcin is a cytosolic Ca2+-binding protein specifically expressed in neutrophils and monocytes/macrophages. It plays a key role in leukocyte-specific functions that are responsible for host defense. Grancalcin can form a heterodimer together with sorcin. Members in this family contain five EF-hand motifs attached to an N-terminal region of variable length containing one or more short Gly/Pro-rich sequences. These proteins form homodimers or heterodimers through pairing between the 5th EF-hands from the two molecules. Unlike calmodulin, the PEF domains do not undergo major conformational changes upon binding Ca2+.

 4-77 3.45e-04

EF-hand, calcium binding motif, found in homologs of mammalian apoptosis-linked gene 2 protein (ALG-2); The family includes some homologs of mammalian apoptosis-linked gene 2 protein (ALG-2) mainly found in lower eukaryotes, such as a parasitic protist Leishmarua major and a cellular slime mold Dictyostelium discoideum. These homologs contains five EF-hand motifs. Due to the presence of unfavorable residues at the Ca2+-coordinating positions, their non-canonical EF4 and EF5 hands may not bind Ca2+. Two Dictyostelium PEF proteins are the prototypes of this family. They may bind to cytoskeletal proteins and/or signal-transducing proteins localized to detergent-resistant membranes named lipid rafts, and occur as monomers or weak homo- or heterodimers like ALG-2. They can serve as a mediator for Ca2+ signaling-related Dictyostehum programmed cell death (PCD).

 122-232 3.60e-04

first calponin homology (CH) domain found in dystrophin and similar proteins; Dystrophin, encoded by the DMD gene, is a large, submembrane cytoskeletal protein that is the main component of the dystrophin-glycoprotein complex (DGC) in skeletal muscles. It links the transmembrane DGC to the actin cytoskeleton through binding strongly to the cytoplasmic tail of beta-dystroglycan, the transmembrane subunit of a highly O-glycosylated cell-surface protein. It is involved in maintaining the structural integrity of cells, as well as in the formation of the blood-brain barrier (BBB). Mutations in dystrophin lead to Duchenne muscular dystrophy (DMD). Moreover, dystrophin deficiency is associated with abnormal cerebral diffusion and perfusion, as well as in acute Trypanosoma cruzi infection. The dystrophin subfamily has been characterized by a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. These domains are believed to be involved in protein-protein interactions. In addition, dystrophin contains two syntrophin binding sites (SBSs) and a long N-terminal extension that comprises two actin-binding calponin homology (CH) domains, approximately 24 spectrin repeats (SRs) and a WW domain. This model corresponds to the first CH domain.

 13-78 5.98e-04

EF-hand, calcium binding motif, found in calretinin (CR); CR, also termed 29 kDa calbindin, is a cytosolic hexa-EF-hand calcium-binding protein predominantly expressed in a variety of normal and tumorigenic t specific neurons of the central and peripheral nervous system. It possibly functions as a calcium buffer, calcium sensor, and apoptosis regulator, which may be implicated in many biological processes, including cell proliferation, differentiation, and cell death. CR contains six EF-hand motifs within two independent domains, CR I-II and CR III-VI. CR I-II consists of EF-hand motifs 1 and 2, and CR III-VI consists of EF-hand motifs 3-6. The first 5 EF-hand motifs are capable of binding calcium ions, while the EF-hand 6 is inactive. Thus, CR has two pairs of cooperative binding sites (I-II and III-IV), which display high affinity calcium-binding sites, and one independent calcium ion-binding site (V), which displays lower affinity binding.

second calponin homology (CH) domain found in the filamin family; The filamin family includes filamin-A (FLN-A), filamin-B (FLN-B) and filamin-C (FLN-C). Filamins function to anchor various transmembrane proteins to the actin cytoskeleton. FLN-A is also called actin-binding protein 280 (ABP-280), alpha-filamin, endothelial actin-binding protein, filamin-1, or non-muscle filamin. It promotes orthogonal branching of actin filaments and links actin filaments to membrane glycoproteins. It also serves as a scaffold for a wide range of cytoplasmic signaling proteins. FLN-B is also called ABP-278, ABP-280 homolog, actin-binding-like protein, beta-filamin, filamin homolog 1 (Fh1), filamin-3, thyroid autoantigen, truncated actin-binding protein, or truncated ABP. It connects cell membrane constituents to the actin cytoskeleton and may also promote orthogonal branching of actin filaments as well as link actin filaments to membrane glycoproteins. FLN-C, also called FLNc, ABP-280-like protein, ABP-L, actin-binding-like protein, filamin-2, or gamma-filamin, is a muscle-specific filamin that plays a central role in muscle cells, probably by functioning as a large actin-cross-linking protein. It may be involved in reorganizing the actin cytoskeleton in response to signaling events, and may also display structural functions at the Z lines in muscle cells. FLN-C is critical for normal myogenesis and for maintaining the structural integrity of the muscle fibers. This family also includes Drosophila melanogaster protein jitterbug (Jbug), which is an actin-meshwork organizing protein containing three copies of the CH domain. Other members of this family contain two copies of the CH domain. This model corresponds to the second CH domain. CH domains are actin filament (F-actin) binding motifs.

 13-75 6.87e-04

Penta-EF hand, calcium binding motifs, found in PEF calpain family; The PEF calpain family belongs to the second group of penta-EF hand (PEF) proteins. It includes classical (also called conventional or typical) calpain (referring to a calcium-dependent papain-like enzymes, EC 3.4.22.17) large catalytic subunits (CAPN1, 2, 3, 8, 9, 11, 12, 13, 14) and two calpain small subunits (CAPNS1 and CAPNS2), which are largely confined to animals (metazoans). These PEF-containing are nonlysosomal intracellular calcium-activated intracellular cysteine proteases that play important roles in the degradation or functional modulation in a variety of substrates in response to calcium signalling. The classical mu- and m-calpains are heterodimers consisting of homologous but a distinct (large) L-subunit/chain (CAPN1 or CAPN2) and a common (small) S-subunit/chain (CAPNS1 or CAPNS2). These L-subunits (CAPN1 and CAPN2) and S-subunit CAPNS1 are ubiquitously found in all tissues. Other calpains likely consist of an isolated L-subunit/chain alone. Many of them, such as CAPNS2, CAPN3 (in skeletal muscle, or lens), CAPN8 (in stomach), CAPN9 (in digestive tracts), CAPN11 (in testis), CAPN12 (in follicles), are tissue-specific and have specific functions in distinct organs. The L-subunits of similar structure (called CALPA and B) also have been found in Drosophila melanogaster. The S-subunit seems to have a chaperone-like function for proper folding of the L-subunit. The catalytic L-subunits contain a short N-terminal anchor helix, followed by a calpain cysteine protease (CysPc) domain, a C2-domain-like (C2L) domain, and a C-terminal Ca2+-binding penta-EF-hand (PEF) domain. The S-subunits only have the PEF domain following an N-terminal Gly-rich hydrophobic domain. The calpains undergo a rearrangement of the protein backbone upon Ca2+-binding.

 18-78 9.56e-04

EF-hand, calcium binding motif, found in secretagogin (SCGN); SCGN is a six EF-hand calcium-binding protein expressed in neuroendocrine, pancreatic endocrine and retinal cells. It plays a crucial role in cell apoptosis, receptor signaling and differentiation. It is also involved in vesicle secretion through binding to various proteins, including interacts with SNAP25, SNAP23, DOC2alpha, ARFGAP2, rootletin, KIF5B, beta-tubulin, DDAH-2, ATP-synthase and myeloid leukemia factor 2. SCGN functions as a calcium sensor/coincidence detector modulating vesicular exocytosis of neurotransmitters, neuropeptides or hormones. It also serves as a calcium buffer in neurons. Thus, SCGN may be linked to the pathogenesis of neurological diseases such as Alzheimer's, and also acts as a serum marker of neuronal damage, or as a tumor biomarker. SCGN consists of the three globular domains each of which contains a pair of EF-hand motifs. All six EF hand motifs of SCGN in some eukaryotes, including D. rerio, X. laevis, M. domestica, G. gallus, O. anatinus, could potentially bind six calcium ions. In contrast, SCGNs from higher eukaryotes have at least one non-functional EF-hand motif due to the mutation(s) or deletions. For instance, the EF1 loop does not coordinate calcium ion due to the key residue asparagine replaced by lysine in SCGNs of many mammalian species. Moreover, the EF2 loop seems to be competent for calcium-binding in most mammalian SCGNs except for human and chimpanzee orthologs.

 122-232 1.01e-03

first calponin homology (CH) domain found in spectrin beta chain, non-erythrocytic 1 (SPTBN1) and similar proteins; Spectrin is an actin crosslinking and molecular scaffold protein that links the plasma membrane to the actin cytoskeleton, and functions in the determination of cell shape, arrangement of transmembrane proteins, and organization of organelles. It is composed of two antiparallel dimers of alpha- and beta- subunits. SPTBN1, also called beta-II spectrin, fodrin beta chain, or spectrin, non-erythroid beta chain 1, is also a component of fodrin, which is the general spectrin-like protein that seems to be involved in secretion. Fodrin interacts with calmodulin in a calcium-dependent manner and is thus a candidate for the calcium-dependent movement of the cytoskeleton at the membrane. SPTBN1 contains two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

 15-91 1.24e-03

EF-hand, calcium binding motif, found in peflin and similar proteins; Peflin, also termed penta-EF hand (PEF) protein with a long N-terminal hydrophobic domain, or penta-EF hand domain-containing protein 1, is a ubiquitously expressed 30-kD PEF protein containing five EF-hand motifs in its C-terminal domain and a longer N-terminal hydrophobic domain (NHB domain) than any other member of the PEF family. The NHB domain harbors nine repeats of a nonapeptide (A/PPGGPYGGP). Peflin may modulate the function of ALG-2 in Ca2+ signaling. It exists only as a heterodimer with ALG-2, and binds two Ca2+ ions through its EF1 and EF3 hands. Its additional EF5 hand is unpaired and does not bind Ca2+ ion but mediates the heterodimerization with ALG-2. The dissociation of heterodimer occurs in the presence of Ca2+. In lower vertebrates, peflin may interact with transient receptor potential N (TRPN1), suggesting a potential role of peflin in fast transducer channel adaptation.

 4-75 1.47e-03

Penta-EF hand, calcium binding motifs, found in Drosophila melanogaster calpain-A (CalpA), calpain-B (CalpB), and similar proteins; The family contains two calpains that have been found in Drosophila, CalpA and CalpB. CalpA, also termed calcium-activated neutral proteinase A (CANP A), or calpain-A catalytic subunit, is a Drosophila calpain homolog specifically expressed in a few neurons in the central nervous system, in scattered endocrine cells in the midgut, and in blood cells. CalpB, also termed calcium-activated neutral proteinase B (CANP B), contains calpain-B catalytic subunit 1 and calpain-B catalytic subunit 2. Both CalpA and CalpB are closely related to that of vertebrate calpains, and they share similar domain architecture, which consists of four domains: the N-terminal domain I, the catalytic domain II carrying the three active site residues, Cys, His and Asn, the Ca2+-regulated phospholipid-binding domain III, and penta-EF-hand Ca2+-binding domain IV. Besides, CalpA and CalpB display some distinguishing structural features that are not found in mammalian typical calpains. CalpA harbors a 76 amino acid long hydrophobic stretch inserted in domain IV, which may be involved in membrane attachment of this enzyme. CalpB has an unusually long N-terminal tail of 224 amino acids, which belongs to the class of intrinsically unstructured proteins (IUP) and may become ordered upon binding to target protein(s). Moreover, they do not need small regulatory subunits for their catalytic activity, and their proteolytic function is not regulated by an intrinsic inhibitor as the Drosophila genome contains neither regulatory subunit nor calpastatin orthologs. As a result, they may exist as a monomer or perhaps as a homo- or heterodimer together with a second large subunit. Furthermore, both CalpA and CalpB are dispensable for viability and fertility and do not share vital functions during Drosophila development. Phosphatidylinositol 4,5-diphosphate, phosphatidylinositol 4-monophosphate, phosphatidylinositol, and phosphatidic acid can stimulate the activity and the rate of activation of CalpA, but not CalpB. Calpain A modulates Toll responses by limited Cactus/IkappaB proteolysis. CalpB directly interacts with talin, an important component of the focal adhesion complex, and functions as an important modulator in border cell migration within egg chambers, which may act via the digestion of talin. CalpB can be phosphorylated by cAMP-dependent protein kinase (protein kinase A, PKA; EC 2.7.11.11) at Ser240 and Ser845, as well as by mitogen-activated protein kinase (ERK1 and ERK2; EC 2.7.11.24) at Thr747. The activation of the ERK pathway by extracellular signals results in the phosphorylation and activation of calpain B. In Schneider cells (S2), calpain B was mainly in the cytoplasm and upon a rise in Ca2+ the enzyme adhered to intracellular membranes.

first calponin homology (CH) domain found in filamins; The filamin family includes filamin-A (FLN-A), filamin-B (FLN-B) and filamin-C (FLN-C). Filamins function to anchor various transmembrane proteins to the actin cytoskeleton. FLN-A is also called actin-binding protein 280 (ABP-280), alpha-filamin, endothelial actin-binding protein, filamin-1, or non-muscle filamin. It promotes orthogonal branching of actin filaments and links actin filaments to membrane glycoproteins. It also serves as a scaffold for a wide range of cytoplasmic signaling proteins. FLN-B is also called ABP-278, ABP-280 homolog, actin-binding-like protein, beta-filamin, filamin homolog 1 (Fh1), filamin-3, thyroid autoantigen, truncated actin-binding protein, or truncated ABP. It connects cell membrane constituents to the actin cytoskeleton and may also promote orthogonal branching of actin filaments as well as link actin filaments to membrane glycoproteins. FLN-C, also called FLNc, ABP-280-like protein, ABP-L, actin-binding-like protein, filamin-2, or gamma-filamin, is a muscle-specific filamin that plays a central role in muscle cells, probably by functioning as a large actin-cross-linking protein. It may be involved in reorganizing the actin cytoskeleton in response to signaling events, and may also display structural functions at the Z lines in muscle cells. FLN-C is critical for normal myogenesis and for maintaining the structural integrity of the muscle fibers. Members of this family contain two copies of the CH domain. The model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

calponin homology (CH) domain found in LIM domain only protein 7 and similar proteins; This family includes LIM domain only protein 7 (LMO-7) and LIM and calponin homology domains-containing protein 1 (LIMCH1), and similar proteins. LMO-7, also called F-box only protein 20, or LOMP, is a transcription regulator for expression of many Emery-Dreifuss muscular dystrophy (EDMD)-relevant genes. It binds to alpha-actinin and AF6/afadin at adherens junctions for epithelial cell-cell adhesion. LIMCH1 acts as an actin stress fiber-associated protein that activates the non-muscle myosin IIa complex by promoting the phosphorylation of its regulatory subunit MRLC/MYL9. It positively regulates actin stress fiber assembly and stabilizes focal adhesions, and therefore negatively regulates cell spreading and cell migration. Members of this family contain a single copy of the CH domain at the N-terminus. CH domains are actin filament (F-actin) binding motifs.

first calponin homology (CH) domain found in the plastin/fimbrin family; This family includes plastin and fimbrin. Plastin has three isoforms, plastin-1, -2, and -3, which are all actin-bundling proteins. Plastin-1, also called intestine-specific plastin, or I-plastin, is an actin-bundling protein in the absence of calcium. Plastin-2, also called L-plastin, LC64P, or lymphocyte cytosolic protein 1 (LCP-1), plays a role in the activation of T-cells in response to costimulation through TCR/CD3 and CD2 or CD28. It modulates the cell surface expression of IL2RA/CD25 and CD69. Plastin-3, also called T-plastin, is found in intestinal microvilli, hair cell stereocilia, and fibroblast filopodia. It may play a role in the regulation of bone development. Fimbrin has been found in plants and fungi. Arabidopsis thaliana fimbrin (AtFIM) includes fimbrin-1, -2, -3, -4, and -5; they cross-link actin filaments (F-actin) in a calcium independent manner. They stabilize and prevent F-actin depolymerization mediated by profilin. They act as key regulators of actin cytoarchitecture, probably involved in cell cycle, cell division, cell elongation and cytoplasmic tractus. AtFIM5 is an actin bundling factor that is required for pollen germination and pollen tube growth. Fungal fimbrin binds to actin, and functionally associates with actin structures involved in the development and maintenance of cell polarity. Members of this family contain four copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.

 13-83 3.91e-03

The penta-EF hand (PEF) family; The penta-EF hand (PEF) family contains a group of five EF-hand calcium-binding proteins, including several classical calpain large catalytic subunits (CAPN1, 2, 3, 8, 9, 11, 12, 13, 14), two calpain small subunits (CAPNS1 and CAPNS2), as well as non-calpain PEF proteins, ALG-2 (apoptosis-linked gene 2, also termed programmed cell death protein 6, PDCD6), peflin, sorcin, and grancalcin. Based on the sequence similarity of EF1 hand, ALG-2 and peflin have been classified into group I PEF proteins. Calcium-dependent protease calpain subfamily members, sorcin and grancalcin, are group II PEF proteins. Calpains (EC 3.4.22.17) are calcium-activated intracellular cysteine proteases that play important roles in the degradation or functional modulation in a variety of substrates. They have been implicated in a number of physiological processes such as cell cycle progression, remodeling of cytoskeletal-cell membrane attachments, signal transduction, gene expression and apoptosis. ALG-2 is a pro-apoptotic factor that forms a homodimer in the cell or a heterodimer with its closest paralog peflin through their EF5s. Peflin is a 30-kD PEF protein with a longer N-terminal hydrophobic domain than any other member of the PEF family, and it contains nine nonapeptide (A/PPGGPYGGP) repeats. It exists only as a heterodimer with ALG-2. The dissociation of heterodimer occurs in the presence of Ca2+. ALG-2 interacts with various proteins in a Ca2+-dependent manner. Sorcin (for soluble resistance-related calcium binding protein) is a soluble resistance-related calcium-binding protein that participates in the regulation of calcium homeostasis in cells. Grancalcin is a cytosolic Ca2+-binding protein specifically expressed in neutrophils and monocytes/macrophages. It plays a key role in leukocyte-specific functions that are responsible for host defense. Grancalcin can form a heterodimer together with sorcin. Members in this family contain five EF-hand motifs attached to an N-terminal region of variable length containing one or more short Gly/Pro-rich sequences. These proteins form homodimers or heterodimers through pairing between the 5th EF-hands from the two molecules. Unlike calmodulin, the PEF domains do not undergo major conformational changes upon binding Ca2+.

 159-205 5.06e-03

calponin homology (CH) domain found in Drosophila melanogaster muscle-specific protein 20 (dMP20) and similar domains; This subfamily contains Drosophila melanogaster muscle-specific protein 20 (dMP20), Echinococcus granulosus myophilin, Dictyostelium discoideum Rac guanine nucleotide exchange factor B (also called Trix), and similar proteins. dMP20 is present only in the synchronous muscles of D. melanogaster. It may be involved in the system linking the nerve impulse with the contraction or the relaxation process. Trix is involved in the regulation of the late steps of the endocytic pathway. dMP20 contains a single copy of the CH domain, while Trix (triple CH-domain array exchange factor) contains three, two type 3 CH domains which are included in this model, and one type 1 CH domain that is not included in this subfamily, but is part of the superfamily. CH domains are actin filament (F-actin) binding motifs.

 122-232 5.85e-03

first calponin homology (CH) domain found in utrophin and similar proteins; Utrophin, also called dystrophin-related protein 1 (DRP-1), is an autosomal dystrophin homolog that increases dystrophic muscle function and reduces pathology. It is broadly expressed in both the mRNA and protein levels, and occurs in the cerebrovascular endothelium. Utrophin forms the utrophin-glycoprotein complex (UGC) by interacting with dystroglycans (DGs) and sarcoglycan-dystroglycans, as well as sarcoglycan and sarcospan (SG-SSPN) subcomplexes. It may act as a scaffolding protein that stabilizes lipid microdomains and clusters mechanosensitive channel subunits, and link the F-actin cytoskeleton to the cell membrane via the associated glycoprotein complex. Like dystrophin, utrophin has a compact cluster of domains comprising four EF-hand-like motifs and a ZZ-domain, followed by a looser region with two coiled-coils. These domains are believed to be involved in protein-protein interactions. In addition, it contains two syntrophin binding sites (SBSs) and a long N-terminal extension that comprises two actin-binding calponin homology (CH) domains, up to 24 spectrin repeats (SRs), and a WW domain. However, utrophin lacks the intrinsic microtubule binding activity of dystrophin SRs. This model corresponds to the first CH domain.

 272-367 8.95e-03

first calponin homology (CH) domain found in the beta spectrin family; The beta spectrin family includes beta-I, -II, -III, -IV and -V spectrins. Spectrin is an actin crosslinking and molecular scaffold protein that links the plasma membrane to the actin cytoskeleton, and functions in the determination of cell shape, arrangement of transmembrane proteins, and organization of organelles. It is composed of two antiparallel dimers of alpha- and beta- subunits. Beta-I spectrin, also called spectrin beta chain, erythrocytic (SPTB), may be involved in anaemia pathogenesis. Beta-II spectrin, also called spectrin beta chain, non-erythrocytic 1 (SPTBN1), or fodrin beta chain, is a component of fodrin, which is the general spectrin-like protein that seems to be involved in secretion. Fodrin interacts with calmodulin in a calcium-dependent manner and is thus a candidate for the calcium-dependent movement of the cytoskeleton at the membrane. Beta-IV spectrin is also called spectrin, non-erythroid beta chain 3 (SPTBN3) or spectrin beta chain, non-erythrocytic 4 (SPTBN4). Its mutation associates with congenital myopathy, neuropathy, and central deafness. Beta-III spectrin is also called spectrin beta chain, non-erythrocytic 2 (SPTBN2), or spinocerebellar ataxia 5 protein (SCA5). Beta-V spectrin, also called spectrin beta chain, non-erythrocytic 5 (SPTBN5), is a mammalian ortholog of Drosophila beta H spectrin. Beta-III and Beta-V spectrins may play crucial roles as longer actin-membrane cross-linkers or fulfill the need for greater extensible flexibility than can be provided by the other smaller conventional spectrins. Members of this family contain two copies of the CH domain. This model corresponds to the first CH domain. CH domains are actin filament (F-actin) binding motifs.
