M1110F3_PURE_PCSK9_Antibody_WB_070215
Recombinant mouse PCSK9 (lane 1, 50 ng) and recombinant human PCSK9 (lane 2, 50 ng) were resolved by electrophoresis, transferred to nitrocellulose, and probed with purified monoclonal anti-PCSK9 antibody (clone M1110F3). Proteins were visualized using a goat anti-rat-IgG secondary antibody conjugated to HRP and chemiluminescence detection.

Description

Proprotein convertase subtilisin/kexin 9 (PCSK9) possesses a signal peptide, a prosegment, a catalytic domain, a hinge region, and a C-terminal Cys-His-rich domain. This protein is primarily synthesized and secreted by hepatocytes. Besides the liver, it is also expressed in the small intestine, kidney, and brain. It is also present in the plasma. Upon translocation to the endoplasmic reticulum, the prosegment of PCSK9 is autocatalytically cleaved and secreted as a stable, enzymatically inactive, non-covalent complex. Elevated low density lipoprotein-cholesterol (LDLc) level is a major risk factor for cardiovascular disease and atherosclerosis. PCSK9 is a regulator of LDLc levels through the binding of LDLR, which subsequently leads to the degradation of LDLR. PCSK9 null mice fed with a high fat diet demonstrated a four-fold decrease in cholesterol accumulation, which stresses the important role played by PCSK9 in the development of cardiovascular disesases. PCS59 also binds to other LDLR family members such as very low density lipoprotein receptor (VLDLR), apolipoprotein E receptor (LRP1/APOER), and apolipoprotein receptor 2 (LRP8/APOER2), which leads to their degradation in the intracellular acidic compartments. Like the LDLR, gene expression of PCSK9 is positively regulated by sterol regulatory element-binding protein 2 (SREBP-2), which is a transcription factor that is activated in response to cellular cholesterol depletion.
