202-262 4.25e-38

Basic leucine zipper (bZIP) domain of CCAAT/enhancer-binding protein epsilon (CEBPE): a DNA-binding and dimerization domain; CEBPE is a critical regulator of terminal granulocyte differentiation or granulopoiesis. It is expressed only in myeloid cells. Mice deficient with CEBPE are normal at birth and fertile, but they do not produce normal neutrophils or eosinophils, and show impaired inflammatory and bacteriocidal responses. Functional loss of CEBPE causes the rare congenital disorder, Neutrophil-specific granule deficiency (SGD), which is characterized by patients' neutrophils with atypical nuclear morphology, abnormal migration and bactericidal activity, and the lack of specific granules. Patients with SGD suffer from severe and frequent bacterial infections. CEBPs (or C/EBPs) are Basic leucine zipper (bZIP) transcription factors that regulate many cellular processes. There are six CEBP proteins in mammalian cells including CEBPA (alpha), CEBPB (beta), CEBPG (gamma), CEBPD (delta), and CEBPE (epsilon), which all contain highly conserved bZIP domains at their C-termini and variations at their N-terminal regions. bZIP factors act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes. The bZIP structural motif contains a basic region and a leucine zipper, composed of alpha helices with leucine residues 7 amino acids apart, which stabilize dimerization with a parallel leucine zipper domain. Dimerization of leucine zippers creates a pair of the adjacent basic regions that bind DNA and undergo conformational change. Dimerization occurs in a specific and predictable manner resulting in hundreds of dimers having unique effects on transcription.

197-267 1.43e-35

Basic leucine zipper (bZIP) domain of CCAAT/enhancer-binding protein beta (CEBPB): a DNA-binding and dimerization domain; CEBPB is a key regulator of metabolism, adipocyte differentiation, myogenesis, and macrophage activation. It is expressed as three distinct isoforms from an intronless gene through alternative translation initiation: CEBPB1 (or liver-enriched activator protein 1, LAP1); CEBPB2 (OR LAP2); and CEBPB3 (or liver-enriched inhibitory protein, LIP). LAP1/2 function as transcriptional activators while LIP is a repressor due to its lack of a transactivation domain. The relative expression of LAP and LIP has effects on inflammation, ER stress, and insulin resistance. CEBPs (or C/EBPs) are Basic leucine zipper (bZIP) transcription factors that regulate many cellular processes. There are six CEBP proteins in mammalian cells including CEBPA (alpha), CEBPB (beta), CEBPG (gamma), CEBPD (delta), and CEBPE (epsilon), which all contain highly conserved bZIP domains at their C-termini and variations at their N-terminal regions. bZIP factors act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes.

Basic leucine zipper (bZIP) domain of CCAAT/enhancer-binding protein delta (CEBPD): a DNA-binding and dimerization domain; CEBPD is an inflammatory response gene that is induced by Toll-like receptor 4 (TLR4) and is essential in the expression of many lipopolysaccharide (LPS)-induced genes and the clearance of bacterial infection. Its expression is increased in response to various extracellular stimuli and it induces growth arrest and apoptosis in cancer cells. It is thought to function as a tumor suppressor and its expression is found reduced by site-specific methylation in many cancers including breast, cervical, and hepatocellular carcinoma. CEBPs (or C/EBPs) are Basic leucine zipper (bZIP) transcription factors that regulate many cellular processes. There are six CEBP proteins in mammalian cells including CEBPA (alpha), CEBPB (beta), CEBPG (gamma), CEBPD (delta), and CEBPE (epsilon), which all contain highly conserved bZIP domains at their C-termini and variations at their N-terminal regions. bZIP factors act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes.

202-261 9.18e-22

Basic leucine zipper (bZIP) domain of CCAAT/enhancer-binding protein gamma (CEBPG): a DNA-binding and dimerization domain; CEBPG is an important regulator of cellular senescence; mouse embryonic fibroblasts deficient of CEBPG proliferated poorly, entered senescence prematurely, and expressed elevated levels of proinflammatory genes. It is also the primary transcription factor that regulates antioxidant and DNA repair transcripts in normal bronchial epithelial cells. In a subset of AML patients with CEBPA hypermethylation, CEBPG is significantly overexpressed. CEBPG is the shortest CEBP protein and it lacks a transactivation domain. It acts as a regulator and buffering reservoir against the transcriptional activities of other CEBP proteins. CEBPs (or C/EBPs) are Basic leucine zipper (bZIP) transcription factors that regulate many cellular processes. There are six CEBP proteins in mammalian cells including CEBPA (alpha), CEBPB (beta), CEBPG (gamma), CEBPD (delta), and CEBPE (epsilon), which all contain highly conserved bZIP domains at their C-termini and variations at their N-terminal regions. bZIP factors act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes.

207-258 2.54e-13

Basic leucine zipper (bZIP) domain of bZIP transcription factors: a DNA-binding and dimerization domain; Basic leucine zipper (bZIP) factors comprise one of the most important classes of enhancer-type transcription factors. They act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes including cell survival, learning and memory, lipid metabolism, and cancer progression, among others. They also play important roles in responses to stimuli or stress signals such as cytokines, genotoxic agents, or physiological stresses. The bZIP structural motif contains a basic region and a leucine zipper, composed of alpha helices with leucine residues 7 amino acids apart, which stabilize dimerization with a parallel leucine zipper domain.

Basic leucine zipper (bZIP) domain of Hepatic leukemia factor (HLF) and similar proteins: a DNA-binding and dimerization domain; HLF, also called vitellogenin gene-binding protein (VBP) in birds, is a circadian clock-controlled Basic leucine zipper (bZIP) transcription factor which is a direct transcriptional target of CLOCK/BMAL1. It is implicated, together with bZIPs DBP and TEF, in the regulation of genes involved in the metabolism of endobiotic and xenobiotic agents. Triple knockout mice display signs of early aging and suffer premature death, likely due to impaired defense against xenobiotic stress. A leukemogenic translocation results in the chimeric fusion protein E2A-HLF that results in a rare form of pro-B-cell acute lymphoblastic leukemia (ALL). bZIP factors act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes. The bZIP structural motif contains a basic region and a leucine zipper, composed of alpha helices with leucine residues 7 amino acids apart, which stabilize dimerization with a parallel leucine zipper domain. Dimerization of leucine zippers creates a pair of the adjacent basic regions that bind DNA and undergo conformational change. Dimerization occurs in a specific and predictable manner resulting in hundreds of dimers having unique effects on transcription.

Basic leucine zipper (bZIP) domain of X-box binding protein 1 (XBP1) and similar proteins: a DNA-binding and dimerization domain; XBP1, a member of the Basic leucine zipper (bZIP) family, is the key transcription factor that orchestrates the unfolded protein response (UPR). It is the most conserved component of the UPR and is critical for cell fate determination in response to ER stress. The inositol-requiring enzyme 1 (IRE1)-XBP1 pathway is one of the three major sensors at the ER membrane that initiates the UPR upon activation. IRE1, a type I transmembrane protein kinase and endoribonuclease, oligomerizes upon ER stress leading to its increased activity. It splices the XBP1 mRNA, producing a variant that translocates to the nucleus and activates its target genes, which are involved in protein folding, degradation, and trafficking. bZIP factors act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes. The bZIP structural motif contains a basic region and a leucine zipper, composed of alpha helices with leucine residues 7 amino acids apart, which stabilize dimerization with a parallel leucine zipper domain.

209-261 3.20e-03

Basic leucine zipper (bZIP) domain of BATF proteins: a DNA-binding and dimerization domain; Basic leucine zipper (bZIP) transcription factor ATF-like (BATF or SFA2), BATF2 (or SARI) and BATF3 form heterodimers with Jun proteins. They function as inhibitors of AP-1-driven transcription. Unlike most bZIP transcription factors that contain additional domains, BATF and BATF3 contain only the the bZIP DNA-binding and dimerization domain. BATF2 contains an additional C-terminal domain of unknown function. BATF:Jun hetrodimers preferentially bind to TPA response elements (TREs) with the consensus sequence TGA(C/G)TCA, and can also bind to a TGACGTCA cyclic AMP response element (CRE). In addition to negative regulation, BATF proteins also show positive transcriptional activities in the development of classical dendritic cells and T helper cell subsets, and in antibody production. bZIP factors act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes. The bZIP structural motif contains a basic region and a leucine zipper, composed of alpha helices with leucine residues 7 amino acids apart, which stabilize dimerization with a parallel leucine zipper domain. Dimerization of leucine zippers creates a pair of the adjacent basic regions that bind DNA and undergo conformational change. Dimerization occurs in a specific and predictable manner resulting in hundreds of dimers having unique effects on transcription.

213-258 6.36e-03

Basic leucine zipper (bZIP) domain of Fungal HAC1-like transcription factors: a DNA-binding and dimerization domain; HAC1 (also called Hac1p or HacA) is a bZIP transcription factor that plays a critical role in the unfolded protein response (UPR). The UPR is initiated by the ER-resident protein kinase and endonuclease IRE1, which promotes non-conventional splicing of the HAC1 mRNA, facilitating its translation. HAC1 binds to and activates promoters of genes that encode chaperones and other targets of the UPR. bZIP factors act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes. The bZIP structural motif contains a basic region and a leucine zipper, composed of alpha helices with leucine residues 7 amino acids apart, which stabilize dimerization with a parallel leucine zipper domain. Dimerization of leucine zippers creates a pair of the adjacent basic regions that bind DNA and undergo conformational change.

208-260 7.04e-03

Basic leucine zipper (bZIP) domain of the oncogene Fos (Fos): a DNA-binding and dimerization domain; Fos proteins are members of the activator protein-1 (AP-1) complex, which is mainly composed of Basic leucine zipper (bZIP) dimers of the Jun and Fos families, and to a lesser extent, the activating transcription factor (ATF) and musculoaponeurotic fibrosarcoma (Maf) families. The broad combinatorial possibilities for various dimers determine binding specificity, affinity, and the spectrum of regulated genes. The AP-1 complex is implicated in many cell functions including proliferation, apoptosis, survival, migration, tumorigenesis, and morphogenesis, among others. There are four Fos proteins: c-Fos, FosB, Fos-related antigen 1 (Fra-1), and Fra-2. In addition, FosB also exists as smaller splice variants FosB2 and deltaFosB2. They all contain an N-terminal region and a bZIP domain. c-Fos and FosB also contain a C-terminal transactivation domain which is absent in Fra-1/2 and the smaller FosB variants. Fos proteins can only heterodimerize with Jun and other AP-1 proteins, but cannot homodimerize. Fos:Jun heterodimers are more stable and can bind DNA with more affinity that Jun:Jun homodimers. Fos proteins can enhance the trans-activating and transforming properties of Jun proteins. bZIP factors act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes. The bZIP structural motif contains a basic region and a leucine zipper, composed of alpha helices with leucine residues 7 amino acids apart, which stabilize dimerization with a parallel leucine zipper domain. Dimerization of leucine zippers creates a pair of the adjacent basic regions that bind DNA and undergo conformational change. Dimerization occurs in a specific and predictable manner resulting in hundreds of dimers having unique effects on transcription.
