Anti-PCGF3 antibodies are used in the immunodetection of the protein polycomb group ring finger 3. In humans, the canonical protein has a reported length of 242 amino acid residues and a mass of 28.1 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. PCGF3 is a known component of the Polycomb group (PcG) multiprotein PRC1-like complex, a complex class required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development. Synonyms for this target antigen include RNF3, RNF3A, polycomb group RING finger protein 3, RING finger protein 3A, ring finger protein 3, and DONG1. PCGF3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PCGF3 antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
