Virol. 87:1957-1966(2013). CC -!- FUNCTION: The primary function of this lipase is the hydrolysis of CC triglycerides of circulating chylomicrons and very low density CC lipoproteins (VLDL). Binding to heparin sulfate proteogylcans at CC the cell surface is vital to the function. The apolipoprotein, CC APOC2, acts as a coactivator of LPL activity in the presence of CC lipids on the luminal surface of vascular endothelium. CC {ECO:0000256|RuleBase:RU362020}. CC -!- CATALYTIC ACTIVITY: Triacylglycerol + H(2)O = diacylglycerol + a CC carboxylate. {ECO:0000256|RuleBase:RU362020}. CC -!- SUBUNIT: Homodimer. Interacts with APOC2; the interaction CC activates LPL activity in the presence of lipids. CC {ECO:0000256|RuleBase:RU362020}. CC -!- SUBCELLULAR LOCATION: Cell membrane CC {ECO:0000256|RuleBase:RU362020}; Lipid-anchor, GPI-anchor CC {ECO:0000256|RuleBase:RU362020}. Secreted CC {ECO:0000256|RuleBase:RU362020}. Note=Locates to the plasma CC membrane of microvilli of hepatocytes with triacyl-glycerol-rich CC lipoproteins (TRL). Some of the bound LPL is then internalized and CC located inside non-coated endocytic vesicles. CC {ECO:0000256|RuleBase:RU362020}. CC -!- PTM: Tyrosine nitration after lipopolysaccharide (LPS) challenge CC down-regulates the lipase activity. CC {ECO:0000256|RuleBase:RU362020}. CC -!- SIMILARITY: Belongs to the AB hydrolase superfamily. Lipase CC family. {ECO:0000256|RuleBase:RU362020}. CC -!- SIMILARITY: Contains 1 PLAT domain. CC {ECO:0000256|RuleBase:RU362020}.
