Anti-MAFG antibodies are used in the immunodetection of the protein MAF bZIP transcription factor G. In humans, the canonical protein has a reported length of 162 amino acid residues and a mass of 17.9 kDa. Its subcellular localization is in the nucleus. It is reported to be highly expressed in skeletal muscle. A member of the BZIP protein family, MAFG is known to be involved with in utero embryonic development and the regulation of transcription. Post-translational modifications have been described, including sumoylation and acetylation. Synonyms for this target antigen include transcription factor MafG, basic leucine zipper transcription factor MafG, v-maf avian musculoaponeurotic fibrosarcoma oncogene homolog G, and hMAF. MAFG gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species.
