Anti-BFAR antibodies are used in the immunodetection of the protein bifunctional apoptosis regulator. In humans, the canonical protein has a reported length of 450 amino acid residues and a mass of 52.7 kDa. Its subcellular localization is in the ER. Up to 2 different isoforms have been reported for this protein. It is noted to be expressed highly in the brain, moderately in small intestine, weakly in testes and only faintly in the liver and skeletal muscle. BFAR is known to be involved with the apoptotic pathway. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include RNF47, RING finger protein 47, bifunctional apoptosis inhibitor, and BAR. BFAR gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some BFAR antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
