LDLR Protein crucially binds to LDL, transporting cholesterol through endocytosis. Clustering into clathrin-coated pits initiates internalization. Interactions with DAB2, LDLRAP1, ARRB1, SNX17, and immature PCSK9 contribute to its functional versatility. The NPXY motif interaction is impaired by tyrosine phosphorylation. LDLR Protein, Mouse (Biotinylated, A23V, C27G, HEK293, His) is the recombinant mouse-derived LDLR protein, expressed by HEK293 , with C-His labeled tag and A23V, C27G mutation.
