Anti-HNF4G antibodies are used in the immunodetection of the protein hepatocyte nuclear factor 4 gamma. In humans, the canonical protein has a reported length of 408 amino acid residues and a mass of 45.9 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in the pancreas, kidney, small intestine and testis. A member of the Nuclear hormone receptor protein family, HNF4G is known to be a type of transcription factor. Synonyms for this target antigen include NR2A3, HNF-4-gamma, nuclear receptor subfamily 2 group A member 2, and NR2A2. HNF4G gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of HNF4G antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
