270-329 6.03e-36

Basic leucine zipper (bZIP) domain of Jun proteins and similar proteins: a DNA-binding and dimerization domain; Jun is a member 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 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. 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 Activating Transcription Factor-2 (ATF-2) and similar proteins: a DNA-binding and dimerization domain; ATF-2 is a sequence-specific DNA-binding protein that belongs to the Basic leucine zipper (bZIP) family of transcription factors. In response to stress, it activates a variety of genes including cyclin A, cyclin D, and c-Jun. ATF-2 also plays a role in the DNA damage response that is independent of its transcriptional activity. 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 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. Dimerization of leucine zippers creates a pair of the adjacent basic regions that bind DNA and undergo conformational change.

270-327 5.50e-14

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. 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.

Basic leucine zipper (bZIP) domain of musculoaponeurotic fibrosarcoma (Maf) proteins: a DNA-binding and dimerization domain; Maf proteins are Basic leucine zipper (bZIP) transcription factors that may participate in the activator protein-1 (AP-1) complex, which is implicated in many cell functions including proliferation, apoptosis, survival, migration, tumorigenesis, and morphogenesis, among others. Maf proteins fall into two groups: small and large. The large Mafs (c-Maf, MafA, MafB, NRL) contain an N-terminal transactivation domain, a linker region of varying size, an anxillary DNA-binding domain, and a C-terminal bZIP domain. They function as critical regulators of terminal differentiation in the blood and in many tissues such as bone, brain, kidney, pancreas, and retina. The small Mafs (MafF, MafK, MafG) do not contain a transactivation domain. They form dimers with cap'n'collar (CNC) proteins that harbor transactivation domains, and they act either as activators or repressors depending on their dimerization partner. They play roles in stress response and detoxification pathways. They have been implicated in various diseases such as diabetes, neurological diseases, thrombocytopenia and cancer. 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 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.

Basic leucine zipper (bZIP) domain of Activating Transcription Factor-6 (ATF-6) and similar proteins: a DNA-binding and dimerization domain; ATF-6 is a type I membrane-bound Basic leucine zipper (bZIP) transcription factor that binds to the consensus ER stress response element (ERSE) and enhances the transcription of genes encoding glucose-regulated proteins Grp78, Grp94, and calreticulum. ATF-6 is one of three sensors of the unfolded protein response (UPR) in metazoans; the others being the kinases Ire1 and PERK. It contains an ER-lumenal domain that detects unfolded proteins. In response to ER stress, ATF-6 translocates from the ER to the Golgi with simultaneous cleavage in a process called regulated intramembrane proteolysis (Rip) to its transcriptionally competent form, which enters the nucleus and upregulates target UPR genes. The three UPR sensor branches cross-communicate to form a signaling network. bZIP factors act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes.

272-307 4.58e-04

Basic leucine zipper (bZIP) domain of bZIP transcription factors: a DNA-binding and dimerization domain; uncharacterized subfamily; 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. 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 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.

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.

Basic leucine zipper (bZIP) domain of CREBZF/Zhangfei transcription factor and similar proteins: a DNA-binding and dimerization domain; CREBZF (also called Zhangfei, ZF, LAZip, or SMILE) is a neuronal bZIP transcription factor that is involved in the infection cycle of herpes simplex virus (HSV) and related cellular processes. It suppresses the ability of the HSV transactivator VP16 to initiate the viral replicative cycle. CREBZF has also been implicated in the regulation of the human nerve growth factor receptor trkA and the tumor suppressor p53. 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.

264-327 4.00e-03

Basic leucine zipper (bZIP) domain of small musculoaponeurotic fibrosarcoma (Maf) proteins: a DNA-binding and dimerization domain; Maf proteins are Basic leucine zipper (bZIP) transcription factors that may participate in the activator protein-1 (AP-1) complex, which is implicated in many cell functions including proliferation, apoptosis, survival, migration, tumorigenesis, and morphogenesis, among others. Maf proteins fall into two groups: small and large. The small Mafs (MafF, MafK, and MafG) do not contain a transactivation domain but do harbor the anxillary DNA-binding domain and a C-terminal bZIP domain. They form dimers with cap'n'collar (CNC) proteins that harbor transactivation domains, and they act either as activators or repressors depending on their dimerization partner. CNC transcription factors include NFE2 (nuclear factor, erythroid-derived 2) and similar proteins NFE2L1 (NFE2-like 1), NFE2L2, and NFE2L3, as well as BACH1 and BACH2. Small Mafs play roles in stress response and detoxification pathways. They also regulate the expression of betaA-globin and other genes activated during erythropoiesis. They have been implicated in various diseases such as diabetes, neurological diseases, thrombocytopenia and cancer. Triple deletion of the three small Mafs is embryonically lethal. 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.
