<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

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). 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).5 Publications

The apolipoprotein APOC2 acts as a coactivator of LPL activity (By similarity). Ca2+ binding promotes protein stability and formation of the active homodimer (PubMed:16179346). Interaction with GPIHBP1 protects LPL against inactivation by ANGPTL4 (PubMed:27929370, PubMed:29899144).By similarity3 Publications

Hyperlipoproteinemia 1 (HLPP1)55 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn autosomal recessive metabolic disorder characterized by defective breakdown of dietary fats, impaired clearance of chylomicrons from plasma causing the plasma to have a milky appearance, and severe hypertriglyceridemia. On a normal diet, patients often present with abdominal pain, hepatosplenomegaly, lipemia retinalis, eruptive xanthomata, and massive hypertriglyceridemia, sometimes complicated with acute pancreatitis.

Homodimer (PubMed:16179346, PubMed:26725083, PubMed:11893776) (Probable).

Interacts with GPIHBP1 with 1:1 stoichiometry (PubMed:17997385, PubMed:27929370, PubMed:26725083, PubMed:27811232, PubMed:29899144, PubMed:30559189).

Interacts with APOC2; the interaction activates LPL activity in the presence of lipids (By similarity). Interaction with heparan sulfate proteoglycans is required to protect LPL against loss of activity (PubMed:11342582). Associates with lipoprotein particles in blood plasma (PubMed:11342582, PubMed:11893776).

Interacts with LMF1 and SEL1L; interaction with SEL1L is required to prevent aggregation of newly synthesized LPL in the endoplasmic reticulum (ER), and for normal export of LPL from the ER to the extracellular space (PubMed:25066055).

Interacts with SORL1; SORL1 acts as a sorting receptor, promoting LPL localization to endosomes and later to lysosomes, leading to degradation of newly synthesized LPL (PubMed:21385844).
