Previous GeneCards Identifiers for MAFG Gene
Globin gene expression is regulated through nuclear factor erythroid-2 (NFE2) elements located in enhancer-like locus control regions positioned many kb upstream of alpha- and beta-gene clusters (summarized by Blank et al., 1997 [PubMed 9166829]). NFE2 DNA-binding activity consists of a heterodimer containing a ubiquitous small Maf protein (MafF, MIM 604877; MafG; or MafK, MIM 600197) and the tissue-restricted protein p45 NFE2 (MIM 601490). Both subunits are members of the activator protein-1-like superfamily of basic leucine zipper (bZIP) proteins (see MIM 165160).[supplied by OMIM, Mar 2010]
GeneCards Summary for MAFG Gene
MAFG (V-Maf Avian Musculoaponeurotic Fibrosarcoma Oncogene Homolog G) is a Protein Coding gene. Diseases associated with MAFG include fibrosarcoma. Among its related pathways are Hemostasis and Factors involved in megakaryocyte development and platelet production. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and sequence-specific DNA binding. An important paralog of this gene is MAFA.
UniProtKB/Swiss-Prot for MAFG Gene
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).
