title: Cubilin, a high-density lipoprotein receptor.
abstract: The metabolism of HDL particles is a complex biological process involving various regulating factors in plasma and different cellular receptors. In addition to the well-established scavenger receptor BI-mediated selective HDL-cholesteryl ester uptake in liver and steroidogenic tissues, evidence has been provided that HDL also undergoes holoparticle endocytosis in different tissues. Recently, a novel receptor expressed in various absorptive epithelia was disclosed as a high affinity receptor for endocytosis of HDL and lipid-poor apolipoprotein AI. This receptor, designated cubilin, may play an important role in the renal clearance of filterable apolipoprotein AI/HDL and in the maternal-fetal transport of cholesterol.
