Virol. 87:1957-1966(2013). CC -!- FUNCTION: Key enzyme in triglyceride metabolism. Catalyzes the CC hydrolysis of triglycerides from circulating chylomicrons and very low CC density lipoproteins (VLDL), and thereby plays an important role in CC lipid clearance from the blood stream, lipid utilization and storage. CC Mediates margination of triglyceride-rich lipoprotein particles in CC capillaries. Recruited to its site of action on the luminal surface of CC vascular endothelium by binding to GPIHBP1 and cell surface heparan CC sulfate proteoglycans. {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, ChEBI:CHEBI:15378, CC ChEBI:CHEBI:17855, ChEBI:CHEBI:18035, ChEBI:CHEBI:28868; EC=3.1.1.34; CC Evidence={ECO:0000256|ARBA:ARBA00000137, CC ECO:0000256|RuleBase:RU362020}; CC -!- SUBUNIT: Homodimer. Interacts with APOC2; the interaction activates LPL CC activity in the presence of lipids. {ECO:0000256|RuleBase:RU362020}. CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|RuleBase:RU362020}; CC Peripheral membrane protein {ECO:0000256|RuleBase:RU362020}; CC Extracellular side {ECO:0000256|RuleBase:RU362020}. Secreted CC {ECO:0000256|RuleBase:RU362020}. Secreted, extracellular space, CC extracellular matrix {ECO:0000256|ARBA:ARBA00004498, CC ECO:0000256|RuleBase:RU362020}. Note=Newly synthesized LPL binds to CC cell surface heparan proteoglycans and is then released by heparanase. CC Subsequently, it becomes attached to heparan proteoglycan on CC endothelial cells. Locates to the plasma membrane of microvilli of CC hepatocytes with triglyceride-rich lipoproteins (TRL). Some of the CC bound LPL is then internalized and located inside non-coated endocytic CC vesicles. {ECO:0000256|RuleBase:RU362020}. CC -!- PTM: Tyrosine nitration after lipopolysaccharide (LPS) challenge down- CC regulates the lipase activity. {ECO:0000256|RuleBase:RU362020}. CC -!- SIMILARITY: Belongs to the AB hydrolase superfamily. Lipase family. CC {ECO:0000256|ARBA:ARBA00010701, ECO:0000256|RuleBase:RU004262}. CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of CC feature annotation. {ECO:0000256|PROSITE-ProRule:PRU00152}.
