LDLR Protein, Human (HEK293, Avi-His)

LDLR Protein plays a pivotal role in cholesterol homeostasis, binding to LDL and mediating cellular uptake through endocytosis. Clustering into clathrin-coated pits is essential for internalization. In microbial infection, LDLR acts as a receptor for hepatitis C virus in hepatocytes, emphasizing its dual functionality in cholesterol metabolism and the cellular response to viral infections. LDLR Protein, Human (HEK293, Avi-His) is the recombinant human-derived LDLR protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of LDLR Protein, Human (HEK293, Avi-His) is 767 a.a., with molecular weight of 110-130 kDa.

The LDLR Protein serves as a crucial mediator in cholesterol homeostasis by binding to low-density lipoprotein (LDL), the primary cholesterol-carrying lipoprotein in plasma, and facilitating its cellular uptake through endocytosis. To enable internalization, receptor-ligand complexes must first cluster into clathrin-coated pits. Additionally, in the context of microbial infection, LDLR acts as a receptor for the hepatitis C virus within hepatocytes, although this interaction does not occur through a direct binding with viral proteins. This dual functionality underscores the diverse roles of LDLR in both cholesterol metabolism and the cellular response to viral infections.
