Summary
LPL encodes lipoprotein lipase, which is expressed in heart, muscle, and adipose tissue. LPL functions as a homodimer, and has the dual functions of triglyceride hydrolase and ligand/bridging factor for receptor-mediated lipoprotein uptake. Severe mutations that cause LPL deficiency result in type I hyperlipoproteinemia, while less extreme mutations in LPL are linked to many disorders of lipoprotein metabolism.

Comments

Comment Type Description
Catalytic Activity Triacylglycerol + H(2)O = diacylglycerol + a carboxylate.
Disease Lipoprotein lipase deficiency (LPL deficiency) [MIM
Function 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).
Ptm Tyrosine nitration after lipopolysaccharide (LPS) challenge down-regulates the lipase activity.
Similarity Belongs to the AB hydrolase superfamily. Lipase family.
Similarity Contains 1 PLAT domain. {ECO
Subcellular Location Cell membrane ; Lipid-anchor, GPI-anchor {ECO
Subunit Homodimer (By similarity). Interacts with APOC2; the interaction activates LPL activity in the presence of lipids. Interacts with GPIHBP1. {ECO
