From NCBI Gene:
The protein encoded by this gene is a plasma membrane receptor for high density lipoprotein cholesterol (HDL). The encoded protein mediates cholesterol transfer to and from HDL. In addition, this protein is a receptor for hepatitis C virus glycoprotein E2. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2011]
Receptor for different ligands such as phospholipids, cholesterol ester, lipoproteins, phosphatidylserine and apoptotic cells (PubMed:12016218, PubMed:12519372, PubMed:21226579). Facilitates the flux of free and esterified cholesterol between the cell surface and extracellular donors and acceptors, such as high density lipoproteins (HDL) and to a lesser extent, apoB-containing lipoproteins and modified lipoproteins. Necessary for selective HDL-cholesterol uptake (PubMed:26965621). Probably involved in the phagocytosis of apoptotic cells, via its phosphatidylserine binding activity (PubMed:12016218).
(Microbial infection) Acts as a receptor for hepatitis C virus in hepatocytes and appears to facilitate its cell entry (PubMed:12356718, PubMed:12913001, PubMed:18000990). Binding between SCARB1 and the hepatitis C virus glycoprotein E2 is independent of the genotype of the viral isolate (PubMed:12356718). Mediates uptake of M.fortuitum, E.coli and S.aureus (PubMed:16020694).
