Protein
Lipoprotein lipase

Organism
Ovis aries (Sheep)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at transcript leveli

Functioni

The primary function of this lipase is the hydrolysis of triglycerides of circulating chylomicrons and very low density lipoproteins (VLDL). Binding to heparin sulfate proteogylcans at the cell surface is vital to the function. The apolipoprotein, APOC2, acts as a coactivator of LPL activity in the presence of lipids on the luminal surface of vascular endothelium By similarity.

Catalytic activityi

Triacylglycerol + H2O = diacylglycerol + a carboxylate.

Subcellular locationi

Cell membrane By similarity; Lipid-anchorGPI-anchor By similarity. Secreted By similarity
Note: Locates to the plasma membrane of microvilli of hepatocytes with triacyl-glycerol-rich lipoproteins (TRL). Some of the bound LPL is then internalized and located inside non-coated endocytic vesicles By similarity.
