Anti-Lipoprotein Lipase Antibody, clone 5D2

Lipoprotein lipase (EC 3.1.1.34; UniProt P06858; also known as LPL) is encoded by the LPL gene (Gene ID 280843) in bovine species. Lipoprotein lipase (LPL) catalyzes the hydrolysis of triglycerides in plasma lipoproteins. LPL is produced by adipocytes and myocytes and secreted into the interstitial spaces, where it is bound by GPIHBP1 (a glycosylphosphatidylinositol-anchored protein of capillary endothelial cells) and shuttled to the luminal face of capillaries. The GPIHBP1 LPL complex is crucial for the binding of triglyceride-rich lipoproteins (TRLs) to endothelial cells and the subsequent lipolytic processing of TRLs. TRLs bind only the LPL-GPIHBP1 complex, but not GPIHBP1 alone, on the cell surface. A deficiency of either protein results in severe hypertriglyceridemia (chylomicronemia) and impaired delivery of lipid nutrients to parenchymal cells. Enzymatically active LPL appears to be a non-covalently linked homodimer with a head-to-tail subunit orientation that rapidly dissociates into inactive monomers. However, evidence for enzymatically active monomeric human LPL has also been presented. LPL is produced with a signal peptide sequence (a.a. 1-27), the removal of which yields the mature 448-amino acid (a.a. 28-475) enzyme containing a PLAT (Polycystin-1, Lipoxygenase, Alpha-Toxin) domain (a.a. 341-464) and a heparin-binding domain (a.a. 346-441).

Clone 5D2 specifically reacts with LPL, but not the highly homologous hepatic lipase (HL) (Peterson, J., et al. (1992). J. Lipid Res. 33(8):1165-1170).
