class IX myosin, motor domain; Myosin IX is a processive single-headed motor, which might play a role in signalling. It has a N-terminal RA domain, an IQ domain, a C1_1 domain, and a RhoGAP domain. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

Ras-associating (RA) domain found in Myosin-IXa; Myosin-IXa, also termed myosin-9a (Myo9a), is a single-headed, actin-dependent motor protein of the unconventional myosin IX class. It is expressed in several tissues and is enriched in the brain and testes. Myosin-IXa contains a Ras-associating (RA) domain, a motor domain, a protein kinase C conserved region 1 (C1), and a Rho GTPase activating domain (RhoGAP). Its RA domain is located at its head domain and has the beta-grasp ubiquitin-like fold with unknown function. Myosin-IXa binds the alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptor (AMPAR) GluA2 subunit, and plays a key role in controlling the molecular structure and function of hippocampal synapses. Moreover, Myosin-IXa functions in epithelial cell morphology and differentiation such that its knockout mice develop hydrocephalus and kidney dysfunction. Myosin-IXa regulates collective epithelial cell migration by targeting RhoGAP activity to cell-cell junctions. Myosin-IXa negatively regulates Rho GTPase signaling, and functions as a regulator of kidney tubule function.

IQ (isoleucine-glutamine) motif containing D (IQCD); IQCD, also called dynein regulatory complex protein 10 (DRC10), belongs to the IQ motif-containing protein family which contains a C-terminal conserved IQ motif domain and two coiled-coil domains. The IQ motif ([ILV]QxxxRxxxx[RK]), where x stands for any amino-acid residue, interacts with calmodulin (CaM) in a calcium-independent manner and is present in proteins with a wide diversity of biological functions. The IQCD protein was found to primarily accumulate in the acrosome area of round and elongating spermatids of the testis during late stage of spermiogenesis and was then localized to the acrosome and tail regions of mature spermatozoa. The expression of IQCD follows the trajectory of acrosome development during spermatogenesis. IQCD is associated with neuroblastoma and neurodegenerative diseases, and is reported to interact with the nuclear retinoid X receptor in the presence of 9-cis-retinoic acid, thereby activating the transcriptional activity of the receptor.

class VI myosin, motor domain; Myosin VI is a monomeric myosin, which moves towards the minus-end of actin filaments, in contrast to most other myosins which moves towards the plus-end of actin filaments. It is thought that myosin VI, unlike plus-end directed myosins, does not use a pure lever arm mechanism, but instead steps with a mechanism analogous to the kinesin neck-linker uncoupling model. It has been implicated in a myriad of functions including: the transport of cytoplasmic organelles, maintenance of normal Golgi morphology, endocytosis, secretion, cell migration, border cell migration during development, and in cancer metastasis playing roles in deafness and retinal development among others. While how this is accomplished is largely unknown there are several interacting proteins that have been identified such as disabled homolog 2 (DAB2), GIPC1, synapse-associated protein 97 (SAP97; also known as DLG1) and optineurin, which have been found to target myosin VI to different cellular compartments.

class XXXIV myosin, motor domain; Class XXXIV myosins are composed of an IQ motif, a short coiled-coil region, 5 tandem ANK repeats, and a carboxy-terminal FYVE domain. The myosin classes XXX to XXXIV contain members from Phytophthora species and Hyaloperonospora parasitica. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class II myosin heavy chain 11, motor domain; Myosin motor domain of smooth muscle myosin heavy chain 11 (also called SMMHC, SMHC). The gene product is a subunit of a hexameric protein that consists of two heavy chain subunits and two pairs of non-identical light chain subunits. It functions as a major contractile protein, converting chemical energy into mechanical energy through the hydrolysis of ATP. The gene encoding a human ortholog of rat NUDE1 is transcribed from the reverse strand of this gene, and its 3' end overlaps with that of the latter. Inversion of the MYH11 locus is one of the most frequent chromosomal aberrations found in acute myeloid leukemia. Alternative splicing generates isoforms that are differentially expressed, with ratios changing during muscle cell maturation. Mutations in MYH11 have been described in individuals with thoracic aortic aneurysms leading to acute aortic dissections with patent ductus arteriosus. MYH11 mutations are also thought to contribute to human colorectal cancer and are also associated with Peutz-Jeghers syndrome. The mutations found in human intestinal neoplasia result in unregulated proteins with constitutive motor activity, similar to the mutant myh11 zebrafish. Class II myosins, also called conventional myosins, are the myosin type responsible for producing actomyosin contraction in metazoan muscle and non-muscle cells.

class II myosin heavy chain 13, motor domain; Myosin motor domain of skeletal muscle myosin heavy chain 13 (also called MyHC-eo) in mammals, chicken, and green anole. Myh13 is a myosin whose expression is restricted primarily to the extrinsic eye muscles which are specialized for function in eye movement. Class II myosins, also called conventional myosins, are the myosin type responsible for producing muscle contraction in muscle cells. Myosin II contains two heavy chains made up of the head (N-terminal) and tail (C-terminal) domains with a coiled-coil morphology that holds the two heavy chains together. The intermediate neck domain is the region creating the angle between the head and tail. It also contains 4 light chains which bind the heavy chains in the "neck" region between the head and tail. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. Class-II myosins are regulated by phosphorylation of the myosin light chain or by binding of Ca2+. A cyclical interaction between myosin and actin provides the driving force. Upon ATP binding, the myosin head dissociates from an actin filament. ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

class XVI myosin, motor domain; These XVI type myosins are also known as Neuronal tyrosine-phosphorylated phosphoinositide-3-kinase adapter 3/NYAP3. Myo16 is thought to play a regulatory role in cell cycle progression and has been recently implicated in Schizophrenia. Class XVI myosins are characterized by an N-terminal ankyrin repeat domain and some with chitin synthase domains that arose independently from the ones in the class XVII fungal myosins. They bind protein phosphatase 1 catalytic subunits 1alpha/PPP1CA and 1gamma/PPP1CC. Human Myo16 interacts with ACOT9, ARHGAP26 and PIK3R2 and with components of the WAVE1 complex, CYFIP1 and NCKAP1. The catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Myosins are actin-dependent molecular motors that play important roles in muscle contraction, cell motility, and organelle transport. The head domain is a molecular motor, which utilizes ATP hydrolysis to generate directed movement toward the plus end along actin filaments. A cyclical interaction between myosin and actin provides the driving force. Rates of ATP hydrolysis and consequently the speed of movement along actin filaments vary widely, from about 0.04 micrometer per second for myosin I to 4.5 micrometer per second for myosin II in skeletal muscle. Myosin II moves in discrete steps about 5-10 nm long and generates 1-5 piconewtons of force. Upon ATP binding, the myosin head dissociates from an actin filament.

ATP hydrolysis causes the head to pivot and associate with a new actin subunit. The release of Pi causes the head to pivot and move the filament (power stroke). Release of ADP completes the cycle. CyMoBase classifications were used to confirm and identify the myosins in this hierarchy.

Ras-associating (RA) domain, structurally similar to a beta-grasp ubiquitin-like fold; RA domain-containing proteins function by interacting with Ras proteins directly or indirectly and are involved in various functions ranging from tumor suppression to being oncoproteins. Ras proteins are small GTPases that are involved in cellular signal transduction. The RA domain has the beta-grasp ubiquitin-like (Ubl) fold with low sequence similarity to ubiquitin (Ub); Ub is a protein modifier in eukaryotes that is involved in various cellular processes, including transcriptional regulation, cell cycle control, and DNA repair. RA-containing proteins include RalGDS, AF6, RIN, RASSF1, SNX27, CYR1, STE50, and phospholipase C epsilon.

IQ (isoleucine-glutamine) motif containing D (IQCD); IQCD, also called dynein regulatory complex protein 10 (DRC10), belongs to the IQ motif-containing protein family which contains a C-terminal conserved IQ motif domain and two coiled-coil domains. The IQ motif ([ILV]QxxxRxxxx[RK]), where x stands for any amino-acid residue, interacts with calmodulin (CaM) in a calcium-independent manner and is present in proteins with a wide diversity of biological functions. The IQCD protein was found to primarily accumulate in the acrosome area of round and elongating spermatids of the testis during late stage of spermiogenesis and was then localized to the acrosome and tail regions of mature spermatozoa. The expression of IQCD follows the trajectory of acrosome development during spermatogenesis. IQCD is associated with neuroblastoma and neurodegenerative diseases, and is reported to interact with the nuclear retinoid X receptor in the presence of 9-cis-retinoic acid, thereby activating the transcriptional activity of the receptor.

Ras-associating (RA) domain 2 found in diacylgylcerol kinase theta (DAGK-theta) and similar proteins; DAGK phosphorylates the second messenger diacylglycerol to phosphatidic acid as part of a protein kinase C pathway. DAGK-theta is characterized as a type V DAGK that has three cysteine-rich domains (all other isoforms have two), a proline/glycine-rich domain at its N-terminal, and a proposed Ras-associating (RA) domain. RA domain-containing proteins function by interacting with Ras proteins directly or indirectly and are involved in several different functions ranging from tumor suppression to being oncoproteins. Ras proteins are small GTPases that are involved in cellular signal transduction. The RA domain has a beta-grasp ubiquitin-like (Ubl) fold with low sequence similarity to ubiquitin (Ub). Ub is a protein modifier in eukaryotes that is involved in various cellular processes including transcriptional regulation, cell cycle control, and DNA repair in eukaryotes. There are ten mammalian isoforms of DAGK have been identified to date, these are organized into five categories based on the domain architecture. DAGK-theta also contains a pleckstrin homology (PH) domain. The subcellular localization and the activity of DAGK-theta are regulated in a complex (stimulation- and cell type-dependent) manner. This family corresponds to the second RA domain of DAGK-theta.

Ras-associating (RA) domain 2 found in Afadin; Afadin, also termed ALL1-fused gene from chromosome 6 protein (AF-6), or canoe, is involved in many fundamental signaling cascades in cells. In addition, it is involved in oncogenesis and metastasis. Afadin has multiple domains: from the N-terminus to the C-terminus it has two Ras-associated (RA) domains, a forkhead-associated domain, a dilute domain, a PDZ domain, three proline-rich domains, and an F-actin binding domain. RA domain-containing proteins function by interacting with Ras proteins directly or indirectly and are involved in several different functions ranging from tumor suppression to being oncoproteins. Ras proteins are small GTPases that are involved in cellular signal transduction. The RA domain has a beta-grasp ubiquitin-like (Ubl) fold with low sequence similarity to ubiquitin (Ub). Ub is a protein modifier in eukaryotes that is involved in various cellular processes including transcriptional regulation, cell cycle control, and DNA repair in eukaryotes. Afadin is abundant at cadherin-based adherens junctions in epithelial cells, endothelial cells, and fibroblasts. This family corresponds to the second RA domain of afadin.
