Anti-AGPAT9 antibodies enable researchers to detect and measure the AGPAT9 antigen in biological samples. This target is a reported synonym of the LPCAT1 gene, which encodes lysophosphatidylcholine acyltransferase 1. This protein is known to function in eye development, among other biological roles. The human version of AGPAT9 has a canonical amino acid length of 534 residues and a protein mass of 59.2 kilodaltons. It is reported to be localized in the ER, Golgi, and cell membrane of cells and widely expressed in many tissue types. AGPAT9 is a member of the 1-acyl-sn-glycerol-3-phosphate acyltransferase protein family.
