Basic leucine zipper (bZIP) transcription factors act in networks of homo- and hetero-dimers in the regulation in a diverse set of cellular pathways. Classical leucine zippers have alpha helices with leucine residues 7 amino acids apart, which stabilize dimerization with a parallel leucine zipper domain. Dimerization creates a pair of basic regions that bind DNA and undergo conformational change. GCN4 was identified in Saccharomyces cerevisiae from mutations in a deficiency in activation with the general amino acid control pathway. GCN4 encodes a trans-activator of amino acid biosynthetic genes containing 2 acidic activation domains and a C-terminal bZIP domain, comprised of a basic alpha-helical DNA-binding region and a coiled-coil dimerization region. Length = 54

>PF03131 bZIP_Maf: bZIP Maf transcription factor; InterPro: IPR004826 There are several different types of Maf transcription factors with different roles in the cell
MafG and MafH are small Mafs which lack a putative transactivation domain. They behave as transcriptional repressors when they dimerize among themselves. However they also serve as transcriptional activators by dimerizing with other (usually larger) basic-zipper proteins and recruiting them to specific DNA-binding sites. Maf transcription factors contain a conserved basic region leucine zipper (bZIP) domain, which mediates their dimerization and DNA binding property. Neural retina-specific leucine zipper proteins also belong to this family. Together with the basic region, the Maf extended homology region (EHR), conserved only within the Maf family, defines the DNA binding specific to Mafs. This structure enables Mafs to make a broader area of contact with DNA and to recognise longer DNA sequences. In particular, the two residues at the beginning of helix H2 are positioned to recognise the flanking region []. Small Maf proteins heterodimerize with Fos and may act as competitive repressors of the NF2-E2 transcription factor. In mouse, Maf1 may play an early role in axial patterning. Defects in these proteins are a cause of autosomal dominant retinitis pigmentosa. ; GO: 0003677 DNA binding, 0006355 regulation of transcription, DNA-dependent, 0005634 nucleus; PDB: 2KZ5_A 3A5T_A 1K1V_A 1SKN_P 2WT7_B 2WTY_B.
