| Background | Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a ~74 kDa protein. Crucial player in the regulation of plasma cholesterol homeostasis. Binds to low-density lipid receptor family members: low density lipoprotein receptor (LDLR), very low density lipoprotein receptor (VLDLR), apolipoprotein E receptor (LRP1/APOER) and apolipoprotein receptor 2 (LRP8/APOER2), and promotes their degradation in intracellular acidic compartments. Acts via a non-proteolytic mechanism to enhance the degradation of the hepatic LDLR through a clathrin LDLRAP1/ARH-mediated pathway. May prevent the recycling of LDLR from endosomes to the cell surface or direct it to lysosomes for degradation. Can induce ubiquitination of LDLR leading to its subsequent degradation. PCSK9 is the therapeutic target of evolocumab (Repatha). 1. Poirier, S. et al. (2008) The Journal of biological chemistry 283, 2363-72. PMID: 18039658 2. Nassoury, N. et al.

Flow-cytometry using anti-human PCSK9 antibody.PCSK9 Transfected CHO cells were stained with an irrelevant antibody (Blue Histogram) or an anti-human PCSK9 antibody monoclonal antibody (Catalog # HV275207 ,Green Histogram) at a concentration of 5 µg/ml for 30 mins at RT. After washing, bound antibody was detected using a FITC conjugated goat anti-human antibody (Catalog # HF690414) and cells analysed on a NovoCyte Flow Cytometer.
