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. After internalization , the receptors dissociate from their ligands when they are exposed to lower pH in endosomes .

WebApr 15, 2011 · Abstract Low-density lipoproteins (LDLs) are a good source of cholesterol, which is important in cellular homeostasis and production of steroids. Apolipoprotein B-100 (ApoB-100), the sole protein component of LDL, is known to bind to cell surface LDL receptor (LDLR) or cell surface-bound proteoglycans and to be internalized into cells. WebApr 11, 2024 · However, despite the increase in cell surface receptors, LDL binding was only 2-fold higher in ARH-deficient lymphocytes. Michaely et al. (2004) ... PTB domains of the ARH protein bind to the internalization motif of the LDL receptor. The authors showed that in addition, ARH binds directly to soluble clathrin trimers and to clathrin adaptors. ... high ast alt low albumin
