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.

GeneCards Summary for LPL Gene
LPL (Lipoprotein Lipase) is a Protein Coding gene. Diseases associated with LPL include Hyperlipoproteinemia, Type I and Hyperlipidemia, Familial Combined, 3. Among its related pathways are triacylglycerol biosynthesis and Signaling by GPCR. Gene Ontology (GO) annotations related to this gene include signaling receptor binding and carboxylic ester hydrolase activity. An important paralog of this gene is LIPG.
UniProtKB/Swiss-Prot Summary for LPL Gene
Key enzyme in triglyceride metabolism. Catalyzes the hydrolysis of triglycerides from circulating chylomicrons and very low density lipoproteins (VLDL), and thereby plays an important role in lipid clearance from the blood stream, lipid utilization and storage (PubMed:8675619, PubMed:11342582, PubMed:27578112). Although it has both phospholipase and triglyceride lipase activities it is primarily a triglyceride lipase with low but detectable phospholipase activity (PubMed:7592706, PubMed:12032167). Mediates margination of triglyceride-rich lipoprotein particles in capillaries (PubMed:24726386). Recruited to its site of action on the luminal surface of vascular endothelium by binding to GPIHBP1 and cell surface heparan sulfate proteoglycans (PubMed:11342582, PubMed:27811232).
Lipases are esterase enzymes that catalyze the hydrolysis of ester bonds within hydrophobic lipids. The diverse class of lipase enzymes includes diacylglycerol lipase (DAGL) and lipoprotein lipase (LPL) and endothelial lipase (LIPG).
