Protein Structure
UniProt Annotation
Function Hydrolyzes specifically phosphatidic acid (PA) to produce 2-acyl lysophosphatidic acid (LPA; a potent bioactive lipid mediator) and fatty acid. Does not hydrolyze other phospholipids, like phosphatidylserine (PS), phosphatidylcholine (PC) and phosphatidylethanolamine (PE) or triacylglycerol (TG). {ECO:0000269PubMed:12963729}.
Subcellular Localization Isoform 1: Membrane. Secreted. Note=May associate with lipid draft.Isoform 2: Membrane. Note=May associate with lipid draft.
Disease Associations Hypertriglyceridemia, familial (FHTR) [MIM:145750]: A common inherited disorder in which the concentration of very low density lipoprotein (VLDL) is elevated in the plasma. This leads to increased risk of heart disease, obesity, and pancreatitis. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
Tissue Specificity Expressed in testis. Expressed exclusively at the connecting piece of the sperm. {ECO:0000269PubMed:12719377, ECO:0000269PubMed:12963729}.
