Target

  • 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.

  • Involvement in disease

    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.

  • Sequence similarities

    Belongs to the AB hydrolase superfamily. Lipase family.
    Contains 1 PLAT domain.

  • Post-translational
    modifications

    Tyrosine nitration after lipopolysaccharide (LPS) challenge down-regulates the lipase activity.

  • Cellular localization

    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.

    Answer

    Thank you for your call earlier this week and for your patience while I have been in touch with the lab.

    Ab93898 has been cited for use in Western blot in the literature, but we don't have an in-house protocol.I've attached an article that describes the protocol used (see page 2352). It looks like the authorsalso used 1 ug/mL concentration so I think that is fine for you to continue using. Their secondary antibody was diluted 1:50,000, and the optimal secondary antibody dilution can definitely vary but it might be beneficial to dilute yours further. I noticed that the authors used milk to block, but if the no-protein block is working well then I would recommend continuing to use it.

    I hope this information will be useful, but please let me know if there is anything else that we can do for you, and keep me updated of any progress with the results.

    Question

    We bought the 5D2 lipoprotein lipase antibody (catalog # ab93898) but I need to know what is the sequence the antibody binds or at least if it binds at the N or C terminal. Can you provide me with this information?

    Answer

    I have found a reference that describes characterization of clone 5D2 (ab93898): Detailed characterization of the binding site of the lipoprotein lipase-specific monoclonal antibody 5D2. Chang et al. J Lipid Research 39:2350-2359, 1998 PMID:9831623 http://www.jlr.org/content/39/12/2350.full.pdf+html In brief, the authors state: "In this study we have shown that the LPL-specific MAb 5D2 recognizes each end of a rather long epitope located between amino acids 380 and 410." This range is closer to the C terminus than the N terminus of the full-length lipase, which consists of 475 amino acids including the signal peptide. http://www.uniprot.org/uniprot/P06858 I hope this is helpful. If you have any other questions, please contact us.
