Anti-GPAT2 antibodies are used in the immunodetection of the protein glycerol-3-phosphate acyltransferase 2, mitochondrial. In humans, the canonical protein has a reported length of 795 amino acid residues and a mass of 87.8 kDa. Its subcellular localization is in the mitochondria. Up to 4 different isoforms have been reported for this protein. A member of the GPAT/DAPAT protein family, GPAT2 is known to be involved with fatty acid metabolism. Synonyms for this target antigen include 1-acylglycerol-3-phosphate O-acyltransferase GPAT2 and cancer/testis antigen 123. GPAT2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some GPAT2 antibodies may have been used in research and have associated citations. Immunofluorescence is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunohistochemistry are also common applications.
