  • 機能
    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.
  • 関連疾患
    Defects in LPL are the cause of lipoprotein lipase deficiency (LPL deficiency) [MIM:238600]; also known as familial chylomicronemia or hyperlipoproteinemia type I. LPL deficiency 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.
  • 配列類似性
    Belongs to the AB hydrolase superfamily. Lipase family.
    Contains 1 PLAT domain.
  • 翻訳後修飾
    Tyrosine nitration after lipopolysaccharide (LPS) challenge down-regulates the lipase activity.
  • 細胞内局在
    Cell membrane. Secreted. 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.

  • ab21356 staining Lipoprotein lipase in Mouse small intestine tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 1.5% serum for 30 minutes at 23°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (2 ug/ml) for 14 hours at 4°C. A Biotin-conjugated Goat anti-mouse IgG polyclonal (1/200) was used as the secondary antibody.

  • Overlay histogram showing HeLa cells stained with ab21356 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab21356, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

Cells were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100 and blocked with 5% BSA for 2 hours at 23°C. Samples were incubated with primary antibody (1/500) for 8 hours at 4°C. An Alexa Fluor® 488-conjugated Rat anti-mouse IgG1 polyclonal (1/250) was used as the secondary antibody.
