Anti-PCGF2 antibodies are used in the immunodetection of the protein polycomb group ring finger 2. In humans, the canonical protein has a reported length of 344 amino acid residues and a mass of 37.8 kDa. Its subcellular localization is in the nucleus. It is notably expressed in all tissues examined with high expression found in the placenta lung and kidney and low expression, in the liver, pancreas and skeletal muscle. PCGF2 is known to be a type of transcriptional repressor. Post-translational modifications have been described, including phosphorylation. The PCGF2 gene has been associated with the disease, Turnpenny-Fry syndrome. Synonyms for this target antigen include RNF110, TPFS, ZNF144, polycomb group RING finger protein 2, DNA-binding protein Mel-18, and MEL-18. PCGF2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some PCGF2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
