WebUpon secretion, PCSK9 binds to the LDL receptors on the surface of hepatocytes. The PCSK9/LDL receptor complex then undergoes endocytosis and fusion with lysosomes, which results in their degradation (Figure 1A). Therefore, the PCSK9 enzyme indirectly supports the elevated values of LDL cholesterol in circulation. Synthesized monoclonal ... WebLDL receptor. This cell surface protein recognizes apolipoprotein B-100, present in VLDL, IDL, LDL, and probably apo-E. It is found in almost all cells. The LDL receptor is an integral membrane protein of 115 kDa, with five functionally distinct segments. Domain 1 comprises the N-terminal (280 amino acids) and is projected outside the cell; it ... LDL receptors are clustered in clathrin-coated pits, and coated pits pinch off from the surface to form coated endocytic vesicles that carry LDL into the cell.
