Lectin-like oxidized low-density lipoprotein (LDL) receptor-1 (LOX-1) is an endothelial scavenger receptor that is important for oxidized low-density lipoprotein uptake. LOX-1 functions as an oligomer; however, little is known about the oligomeric complex and ligand processing after recognition by LOX-1. Here, we found that LOX-1 recognized and internalized ligands through the caveolae/raft-dependent endocytosis pathway in human coronary artery endothelial cells. Furthermore, we demonstrated that LOX-1 was palmitoylated and that both cysteine 36 and cysteine 46 were necessary for the recruitment of LOX-1 into raft microdomains and for its ligand uptake ability.
