Anti-CTA antibodies are protein reagents that detect specific antigens. The CTA antigen is another term for the human protein phosphate cytidylyltransferase 1A, choline, encoded by the PCYT1A gene. The protein is known to catalyze the key rate-limiting step in the CDP-choline pathway for phosphatidylcholine biosynthesis. Canonically, it has an amino acid length of 367 residues and a mass of 41.7 kilodaltons. Its subcellular localization is in the membrane, nucleus, ER, and cytoplasm and it is widely expressed in many tissue types. The CTA protein is a member of the Cytidylyltransferase protein family. Other alias names for CTA include CCTA, CCTalpha, and CT. Indicated applications for CTA antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, Immunoprecipitation, and Immunohistochemistry.
