Hydrolyzes 2-acetyl monoalkylglycerol ether (1-O-alkyl-2-acetyl-sn-glycerol), the penultimate precursor of the pathway for de novo synthesis of platelet-activating factor . May be responsible for the hydrolysis of cholesterol esters (such as cholesteryl (9Z-octadecenoate)) in macrophages (By similarity). Also involved in organ detoxification by hydrolyzing exogenous organophosphorus compounds (By similarity). May contribute to cancer pathogenesis by promoting tumor cell migration .
Subcellular locations: Cell membrane, Microsome
Expressed in monocyte-derived macrophages. Up-regulated in invasive melanoma and breast carcinoma cell lines.
