Virol. 87:1957-1966(2013). CC -!- FUNCTION: Key enzyme in triglyceride metabolism. Catalyzes the CC hydrolysis of triglycerides from circulating chylomicrons and very CC low density lipoproteins (VLDL), and thereby plays an important CC role in lipid clearance from the blood stream, lipid utilization CC and storage. Mediates margination of triglyceride-rich lipoprotein CC particles in capillaries. Recruited to its site of action on the CC luminal surface of vascular endothelium by binding to GPIHBP1 and CC cell surface heparan sulfate proteoglycans. CC {ECO:0000256|RuleBase:RU362020}. CC -!- CATALYTIC ACTIVITY: CC Reaction=a triacylglycerol + H2O = a diacylglycerol + a fatty acid CC + H(+); Xref=Rhea:RHEA:12044, ChEBI:CHEBI:15377, CC ChEBI:CHEBI:15378, ChEBI:CHEBI:17855, ChEBI:CHEBI:18035, CC ChEBI:CHEBI:28868; EC=3.1.1.34; CC Evidence={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}; Peripheral membrane protein CC {ECO:0000256|RuleBase:RU362020}; Extracellular side CC {ECO:0000256|RuleBase:RU362020}. Secreted CC {ECO:0000256|RuleBase:RU362020, ECO:0000256|SAAS:SAAS00553472}. CC Secreted, extracellular space, extracellular matrix CC {ECO:0000256|RuleBase:RU362020}. Note=Newly synthesized LPL binds CC to cell surface heparan proteoglycans and is then released by CC heparanase. Subsequently, it becomes attached to heparan CC proteoglycan on endothelial cells. Locates to the plasma membrane CC of microvilli of hepatocytes with triglyceride-rich lipoproteins CC (TRL). Some of the bound LPL is then internalized and located CC 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:RU004262, CC ECO:0000256|SAAS:SAAS00591292}.
