Anti-abhydrolase domain containing 5, lysophosphatidic acid acyltransferase antibodies are used for the immunodetection of the protein encoded by the ABHD5 gene. In humans, the canonical protein has a reported length of 349 amino acid residues and a mass of 39.1 kDa. Its subcellular localization is in the cytoplasm. It is found to be widely expressed in various tissues, including lymphocytes, liver, skeletal muscle and brain. A member of the Peptidase S33 protein family, it is known to be involved with cell differentiation and fatty acid metabolism. The gene encoding this protein is implicated in Chanarin-Dorfman syndrome. Other names for this target antigen include IECN2, NCIE2, 1-acylglycerol-3-phosphate O-acyltransferase ABHD5, abhydrolase domain-containing protein 5, lipid droplet-binding protein CGI-58, and CGI58. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
