178-231 | 2.05e-20 | ||||
Basic leucine zipper (bZIP) domain of Activating Transcription Factor-3 (ATF-3) and similar proteins: a DNA-binding and dimerization domain; ATF-3 is a Basic leucine zipper (bZIP) transcription factor that is induced by various stress signals such as cytokines, genetoxic agents, or physiological stresses. It is implicated in cancer and host defense against pathogens. It negatively regulates the transcription of pro-inflammatory cytokines and is critical in preventing acute inflammatory syndromes. Mice deficient with ATF3 display increased susceptibility to endotoxic shock induced death. ATF3 dimerizes with Jun and other ATF proteins; the heterodimers function either as activators or repressors depending on the promoter context. 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. : Pssm-ID: 269870 Cd Length: 62 Bit Score: 84.82 E-value: 2.05e-20

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.

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 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 three Jun proteins: c-Jun, JunB, and JunD. c-Jun is the most potent transcriptional activator of the AP-1 proteins. Both c-Jun and JunB are essential during development; deletion of either results in embryonic lethality in mice. c-Jun is essential in hepatogenesis and liver erythropoiesis, while JunB is required in vasculogenesis and angiogenesis in extraembryonic tissues. While JunD is dispensable in embryonic development, it is involved in transcription regulation of target genes that help cells to cope with environmental signals. 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 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.

Basic leucine zipper (bZIP) domain of BTB and CNC homolog (BACH) proteins: a DNA-binding and dimerization domain; BACH proteins are Cap'n'Collar (CNC) Basic leucine zipper (bZIP) transcription factors that are defined by a conserved 43-amino acid region (called the CNC domain) located N-terminal to the bZIP DNA-binding domain. In addition, they contain a BTB domain (Broad complex-Tramtrack-Bric-a-brac domain, also known as the POZ [poxvirus and zinc finger] domain) that is absent in other CNC proteins. Veterbrates contain two members, BACH1 and BACH2. BACH1 forms heterodimers with small Mafs such as MafK to function as a repressor of heme oxygenase-1 (HO-1) gene (Hmox-1) enhancers. It has also been implicated as the master regulator of breast cancer bone metastasis. The BACH1 bZIP transcription factor should not be confused with the protein originally named as BRCA1-Associated C-terminal Helicase1 (BACH1), which has been renamed BRIP1 (BRCA1 Interacting Protein C-terminal Helicase1) and also called FANCJ. BACH2 is a B-cell specific transcription factor that plays a critical role in oxidative stress-mediated apoptosis. It plays an important role in class switching and somatic hypermutation of immunoglobulin genes. 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.

Basic leucine zipper (bZIP) domain of blue light (BL) receptor aureochrome (AUREO) and similar bZIP domains; AUREO is a BL-activated transcription factor specific to phototrophic stramenopiles. It has a bZIP and a BL-sensing light-oxygen voltage (LOV) domain. It has been shown to mediate BL-induced branching and regulate the development of the sex organ in Vaucheria frigida. 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. This subgroup also includes the Epstein-Barr virus (EBV) immediate-early transcription factor ZEBRA (BZLF1, Zta, Z, EB1). ZEBRA exhibits a variant of the bZIP fold, it has a unique dimer interface and a substantial hydrophobic pocket; it has a C-terminal moiety which stabilizes the coiled coil involved in dimer formation. ZEBRA functions to trigger the switch of EBV's biphasic infection cycle from latent to lytic infection. It activates the promoters of EBV lytic genes by binding ZEBRA response elements (ZREs) and inducing a cascade of expression of over 50 viral genes. It also down regulates latency-associated promoters, is an essential replication factor, induces host cell cycle arrest, and alters cellular immune responses and transcription factor activity.
