Anti-PCCA antibodies are used in the immunodetection of the protein propionyl-CoA carboxylase subunit alpha. In humans, the canonical protein has a reported length of 728 amino acid residues and a mass of 80.1 kDa. Its subcellular localization is in the mitochondria. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. PCCA is known to be involved with fatty acid metabolism. Synonyms for this target antigen include PCCase alpha subunit, pccA complementation group, propanoyl-CoA:carbon dioxide ligase alpha subunit, propionyl CoA carboxylase, alpha polypeptide, and propionyl-CoA carboxylase alpha chain, mitochondrial. PCCA gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PCCA antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
