Basic leucine zipper (bZIP) domain of large 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, and neural retina leucine zipper or NRL) contain an N-terminal transactivation domain, a linker region of varying size, an anxillary DNA-binding domain, 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. MafA and MafB also play crucial roles in islet beta cells; they regulate genes essential for glucose sensing and insulin secretion cooperatively and sequentially. Large Mafs are also implicated in oncogenesis; MafB and c-Maf chromosomal translocations result in multiple myelomas. 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 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.

Basic leucine zipper (bZIP) domain of Cap'n'Collar (CNC) transcription factors: a DNA-binding and dimerization domain; CNC proteins form a subfamily of 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. This subfamily includes Drosophila Cnc and four vertebrate counterparts, NFE2 (nuclear factor, erythroid-derived 2), NFE2-like 1 or NFE2-related factor 1 (NFE2L1 or Nrf1), NFE2L2 (or Nrf2), and NFE2L3 (or Nrf3). It also includes BACH1 and BACH2, which contain an additional BTB domain (Broad complex###Tramtrack###Bric-a-brac domain, also known as the POZ [poxvirus and zinc finger] domain). CNC proteins function during development and/or contribute in maintaining homeostasis during stress responses. In flies, Cnc functions both in development and in stress responses. In vertebrates, several CNC proteins encoded by distinct genes show varying functions and expression patterns. NFE2 is required for the proper development of platelets while the three Nrfs function in stress responses. Nrf2, the most extensively studied member of this subfamily, acts as a xenobiotic-activated receptor that regulates the adaptive response to oxidants and electrophiles. BACH1 forms heterodimers with small Mafs such as MafK to function as a repressor of heme oxygenase-1 (HO-1) gene (Hmox-1) enhancers. BACH2 is a B-cell specific transcription factor that plays a critical role in oxidative stress-mediated apoptosis. 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.

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.

Basic leucine zipper (bZIP) domain of Plant RF2-like transcription factors: a DNA-binding and dimerization domain; This subfamily is composed of plant bZIP transciption factors with similarity to Oryza sativa RF2a and RF2b, which are important for plant development. They interact with, as homodimers or heterodimers with each other, and activate transcription from the RTBV (rice tungro bacilliform virus) promoter, which is regulated by sequence-specific DNA-binding proteins that bind to the essential cis element BoxII. RF2a and RF2b show differences in binding affinities to BoxII, expression patterns in different rice organs, and subcellular localization. Transgenic rice with increased RF2a and RF2b display increased resistance to rice tungro disease (RTD) with no impact on plant development. 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.
