This secreted protein hydrolyzes phosphatidylserine in liposomes. Three transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, May 2011]. * **UniProt Summary**: Hydrolyzes the ester bond at the sn-1 position of glycerophospholipids and produces 2-acyl lysophospholipids. Hydrolyzes phosphatidylserine (PS) in the form of liposomes and 1- acyl-2 lysophosphatidylserine (lyso-PS), but not triolein, phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidic acid (PA) or phosphatidylinositol (PI). Isoform 2 hydrolyzes lyso-PS but not PS. Hydrolysis of lyso-PS in peritoneal mast cells activated by receptors for IgE leads to stimulate histamine production. {ECO:0000269|PubMed:10196188}. |Lipase| |phosphatidylserine 1-acylhydrolase activity| |phospholipase A1 activity| |acrosomal membrane| |phosphatidylserine acyl-chain remodeling| |lipase activity| |phosphatidylserine metabolic process| |cellular modified amino acid metabolic process| |lipid catabolic process| |glycerophospholipid metabolic process| |phospholipid metabolic process| |glycerolipid metabolic process| |organophosphate metabolic process| |cellular lipid metabolic process| |lipid metabolic process| |extracellular space| |organic substance catabolic process| |extracellular region| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp272|CHIR-124 0.04μM R06 exp272]]|2.29| No correlation found to any other genes in chemogenomics.
