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]
GeneCards Summary for SCARB1 Gene
SCARB1 (Scavenger Receptor Class B Member 1) is a Protein Coding gene. Diseases associated with SCARB1 include Hepatitis C and Hepatitis. Among its related pathways are Regulation of cholesterol biosynthesis by SREBP (SREBF) and Vitamin digestion and absorption. GO annotations related to this gene include protein homodimerization activity and phosphatidylserine binding. An important paralog of this gene is SCARB2.
UniProtKB/Swiss-Prot for SCARB1 Gene
Receptor for different ligands such as phospholipids, cholesterol ester, lipoproteins, phosphatidylserine and apoptotic cells. 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 (By similarity). Necessary for selective HDL-cholesterol uptake (PubMed:26965621). Probably involved in the phagocytosis of apoptotic cells, via its phosphatidylserine binding activity. Receptor for hepatitis C virus glycoprotein E2. Binding between SCARB1 and E2 was found to be independent of the genotype of the viral isolate (By similarity).
(Microbial infection) Acts as a receptor for hepatitis C virus in hepatocytes.
