== Function ==
 +
[https://www.uniprot.org/uniprot/MAFG_MOUSE MAFG_MOUSE] Since they lack a putative transactivation domain, the small Mafs behave as transcriptional repressors when they dimerize among themselves. However, they seem to serve as transcriptional activators by dimerizing with other (usually larger) basic-zipper proteins and recruiting them to specific DNA-binding sites. Small Maf proteins heterodimerize with Fos and may act as competitive repressors of the NF-E2 transcription factor. Transcription factor, component of erythroid-specific transcription factor NF-E2. Activates globin gene expression when associated with NF-E2. May be involved in signal transduction of extracellular H(+) (By similarity).<ref>PMID:9679061</ref> <ref>PMID:16738329</ref>

== Publication Abstract from PubMed ==
 +
The Maf family proteins, which constitute a subgroup of basic region-leucine zipper (bZIP) proteins, function as transcriptional regulators of cellular differentiation. Together with the basic region, the Maf extended homology region (EHR), conserved only within the Maf family, defines the DNA binding specific to Mafs. Here we present the first NMR-derived structure of the DNA-binding domain (residues 1-76) of MafG, which contains the EHR and the basic region. The structure consists of three alpha-helices and resembles the fold of the DNA-binding domain of Skn-1, a developmental transcription factor of Caenorhabditis elegans. The structural similarity between MafG and Skn-1 enables us to propose a possible mechanism by which Maf family proteins recognize their consensus DNA sequences.
