Anti-phospholipase A and acyltransferase 5 antibodies are used for the immunodetection of the protein encoded by the PLAAT5 gene. In humans, the canonical protein has a reported length of 279 amino acid residues and a mass of 30.3 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of the H-rev107 protein family, it is known to be involved with metabolic processes. Other names for this target antigen include H-rev107-like protein 5, HRAS like suppressor family member 5, HRAS-like suppressor 5, calcium-independent phosphatidylethanolamine N-acyltransferase, and Ca(2+)-independent N-acyltransferase. Gene orthologs have been identified in the mouse, rat, bovine and chimpanzee species.
