Anti-MAX dimerization protein MGA antibodies are used for the immunodetection of the protein encoded by the MGA gene. In humans, the canonical protein has a reported length of 3065 amino acid residues and a mass of 336.2 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. It is known to function as a dual-specificity transcription factor, regulating the expression of both MAX-network and T-box family target genes. Other names for this target antigen include MXD5, MAX gene-associated protein, MAX dimerization protein 5, MGA, MAX dimerization protein, and MAD5. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
