Defects in this gene are a cause of susceptibility to familial hypertrigliceridemia. This gene is also expressed at high levels in Ewing family tumor cells. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]. * **UniProt Summary**: 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:0000269|PubMed:12963729}. |Lipase| |phospholipase activity| |lipase activity| |carboxylic ester hydrolase activity| |phosphatidic acid biosynthetic process| |phosphatidic acid metabolic process| |heparin binding| |glycerophospholipid biosynthetic process| |glycerolipid biosynthetic process| |phospholipid biosynthetic process| |lipid catabolic process| |glycerophospholipid metabolic process| |phospholipid metabolic process| |glycerolipid metabolic process| |organophosphate biosynthetic process| |lipid biosynthetic process| |organophosphate metabolic process| |cellular lipid metabolic process| |lipid metabolic process| |extracellular space| |organic substance catabolic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp98|BI-6727 0.04μM R03 exp98]]|-1.82| No correlation found to any other genes in chemogenomics.
