WebApr 14, 1998 · LDL receptors, located in specialized indentations in the cell membrane called coated pits, specifically and tightly bind LDL. After binding, the receptor–lipoprotein complex is internalized by the cells via coated pits and vesicles, and the entire LDL particle is delivered to lysosomes, wherein it is disassembled by enzymatic hydrolysis ... WebThe proposed model explains why there are differences between apoE isoforms with respect to lipid binding and why lipid enhances apoE binding to receptors such as the low-density lipoprotein receptor (LDLR). As such, it opens the way to develop small molecular weight compounds that could preferentially influence the behavior of the apoE isoforms. WebMar 7, 2024 · LRP1 belongs to the LDL receptor family (left). These, and more distantly related cell surface receptors (right), bind a wide range of proteins and play important roles in cholesterol metabolism, endocytosis, and cell signaling in the brain.
