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}.
