Anti-PCYT2 antibodies are used in the immunodetection of the protein phosphate cytidylyltransferase 2, ethanolamine. In humans, the canonical protein has a reported length of 389 amino acid residues and a mass of 43.8 kDa. Up to 4 different isoforms have been reported for this protein. It is reported to be highly expressed in the liver, heart, and skeletal muscle. A member of the Cytidylyltransferase protein family, PCYT2 is reported to be an ethanolamine-phosphate cytidylyltransferase that catalyzes the second step in the synthesis of phosphatidylethanolamine (PE) from ethanolamine via the CDP-ethanolamine pathway. Synonyms for this target antigen include SPG82, ethanolamine-phosphate cytidylyltransferase, CTP:phosphoethanolamine cytidylyltransferase, phosphorylethanolamine transferase, and ET. PCYT2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some PCYT2 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
