Anti-phospholipase A and acyltransferase 1 antibodies are used for the immunodetection of the protein encoded by the PLAAT1 gene. In humans, the canonical protein has a reported length of 168 amino acid residues and a mass of 18.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the H-rev107 protein family, it is known to be involved with lens fiber cell differentiation and the metabolism of lipids. Other names for this target antigen include HRAS like suppressor, HRAS-like suppressor 1, phospholipase A/acyltransferase 1, phospholipid-metabolizing enzyme A-C1, and H-REV107 protein-related protein. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
