Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific.

Gene(ID):

SCARB1(949)

Expression:

Q8WTV0 SCRB1_HUMAN:

Widely expressed.

Description:

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]

Research Backgrounds

Q8WTV0_SCRB1_HUMAN

Function:

Receptor for different ligands such as phospholipids, cholesterol ester, lipoproteins, phosphatidylserine and apoptotic cells. Receptor for HDL, mediating selective uptake of cholesteryl ether and HDL-dependent cholesterol efflux. Also facilitates the flux of free and esterified cholesterol between the cell surface and apoB-containing lipoproteins and modified lipoproteins, although less efficiently than HDL. May be involved in the phagocytosis of apoptotic cells, via its phosphatidylserine binding activity.

(Microbial infection) Acts as a receptor for hepatitis C virus in hepatocytes and appears to facilitate its cell entry. Binding between SCARB1 and the hepatitis C virus glycoprotein E2 is independent of the genotype of the viral isolate. Mediates uptake of M.fortuitum, E.coli and S.aureus.

PTMs:

N-glycosylated.

The six cysteines of the extracellular domain are all involved in intramolecular disulfide bonds.

Subcellular Location:

Cell membrane>Multi-pass membrane protein. Membrane>Caveola>Multi-pass membrane protein.
Note: Predominantly localized to cholesterol and sphingomyelin-enriched domains within the plasma membrane, called caveolae.

Tissue Specificity:

Widely expressed.

Subunit Structure:

The C-terminal region binds to PDZK1.

(Microbial infection) Interacts with hepatitis C virus E1:E2 glycoproteins.

Family&Domains:

Belongs to the CD36 family.
