Binds to ldl receptors
WebLDL Receptor. The 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. The ligand dissociates from the receptor in acidic endosomal vesicles. WebMechanistic studies determined that PCSK9 binds to the LDL receptor (LDLR) and promotes its lysosomal degradation in cells [5–7]. The molecular mapping of the PCSK9-LDLR binding interface aided the development of therapeutic anti-PCSK9 monoclonal antibodies (mAbs) that effectively block this interaction at the cell surface [8,9].

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.
WebApr 11, 2024 · Electronegative LDL (LDL(−)) is a minor form of LDL present in blood for which proportions are increased in pathologies with increased cardiovascular risk. In vitro studies have shown that LDL(−) presents pro-atherogenic properties, including a high susceptibility to aggregation, the ability to induce inflammation and apoptosis, and …
