背景（Background）
lipoprotein lipase(LPL) Homo sapiens 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.

功能
catalytic activity:Triacylglycerol + H(2)O = diacylglycerol + a carboxylate.,disease:Defects in LPL are a cause of familial chylomicronemia [MIM:238600]; also known as hyperlipoproteinemia type I. Familial chylomicronemia is a recessive disorder usually manifesting in childhood. On a normal diet, patients often present with abdominal pain, hepatosplenomegaly, lipemia retinalis, eruptive xanthomata, and massive hypertriglyceridemia, sometimes complicated with acute pancreatitis.,disease:Defects in LPL are the cause of lipoprotein lipase deficiency (LPL deficiency) [MIM:238600]. LPL deficiency leads to hypertriglyceridemia.,function:The primary function of this lipase is the hydrolysis of triglycerides of circulating chylomicrons and very low density lipoproteins (VLDL). The enzyme functions in the presence of apolipoprotein C-2 on the luminal surface of vascular endothelium.,online inform

细胞定位
Cell membrane ; Peripheral membrane protein ; Extracellular side . Secreted . Secreted, extracellular space, extracellular matrix . Newly synthesized LPL binds to cell surface heparan proteoglycans and is then released by heparanase. Subsequently, it becomes attached to heparan proteoglycan on endothelial cells (PubMed:27811232). Locates to the plasma membrane of microvilli of hepatocytes with triglyceride-rich lipoproteins (TRL). Some of the bound LPL is then internalized and located inside non-coated endocytic vesicles (By similarity). .
组织表达
Detected in blood plasma (PubMed:2340307, PubMed:11893776, PubMed:12641539). Detected in milk (at protein level) (PubMed:2340307).
