Anti-GPAT3 antibodies are used in the immunodetection of the protein glycerol-3-phosphate acyltransferase 3. In humans, the canonical protein has a reported length of 434 amino acid residues and a mass of 48.7 kDa. Its subcellular localization is in the ER. It is widely expressed across many tissue types. A member of the 1-acyl-sn-glycerol-3-phosphate acyltransferase protein family, GPAT3 is known to be involved with metabolic processes. GPAT3 is also used as a cellular marker for characterizing astrocytes. Synonyms for this target antigen include 1-AGPAT 9, 1-acyl-sn-glycerol-3-phosphate O-acyltransferase 10, 1-acyl-sn-glycerol-3-phosphate O-acyltransferase 9, 1-acylglycerol-3-phosphate O-acyltransferase 8, and 1-AGP acyltransferase 9. GPAT3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of GPAT3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
