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. WebJan 24, 2024 · LDLR trafficking in an interconnected membrane system (A) Low-density lipoprotein (LDL) receptor (LDLR) bound to its cargo is internalised via clathrin-mediated endocytosis. Within early endosomes (EE) LDLR separates from LDL and is sorted to recycling endosomes (RE) for transport to the plasma membrane. WebThe LDL receptor exists as an oligomeric surface glycoprotein that plays a pivotal role in LDL clearance and cholesterol homeostasis. It binds ligands at the cell surface, after which the ligand-receptor complex is internalized via the classic endocytotic pathway.
