Anti-CEPT1 antibodies are used in the immunodetection of the protein choline/ethanolamine phosphotransferase 1. In humans, the canonical protein has a reported length of 416 amino acid residues and a mass of 46.6 kDa. Its subcellular localization is in the nucleus and ER. It is ubiquitously expressed across many tissue types. A member of the CDP-alcohol phosphatidyltransferase class-I protein family, CEPT1 is known to catalyze both phosphatidylcholine and phosphatidylethanolamine biosynthesis from CDP-choline and CDP-ethanolamine, respectively. Synonyms for this target antigen include choline/ethanolaminephosphotransferase 1 and 1-alkenyl-2-acylglycerol choline phosphotransferase. CEPT1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some CEPT1 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA, Western Blot, and Immunofluorescence are also common applications.
