Background

SR-BI (scavenger receptor class B member 1, SCARB1) belongs to the CD36 family and acts as a cell surface lipoprotein receptor for a variety of ligands including high density lipoprotein (HDL), phospholipids, phosphatidylserine, and lipoproteins such as lipopolysaccharide (LPS). SR-BI mediates selective uptake of HDL cholesteryl (HDL-C) ester in the liver, steroidogenic tissues, and adipose tissue and facilitates the flux of free and esterified cholesterol between the cell surface and apoB-containing lipoproteins and modified lipoproteins. SR-BI plays a role in antigen capture and cross-presentation from bacteria, parasites, and viruses such as Hepatitis C. In endothelial cells and macrophages, SR-BI is involved in anti-inflammatory and pro-survival signaling, providing protection against atherosclerosis and clearing apoptotic cells (efferocytosis) (1, 2).

At least 5 different human splice variants have been identified with theoretical molecular weights ranging from 60.9 kDa for the canonical sequence to 45 kDa for an N-terminally truncated variant (SR-BII) (3). The extracellular domain of human SR-BI (CLA-1) shares 80%, 80%, 89%, 86% and 84% aa sequence identity with mouse, rat, porcine, rabbit, and bovine SR-BI, respectively. SR-BI is highly glycosylated and removal of N-linked glycosylation reduces lipid transport.
