Western blot - Anti-Scavenging Receptor SR-BI antibody [25/CLA-1] (AB300632)

False colour image of Western blot : Anti-Scavenging Receptor SR-BI antibody [25/CLA-1] staining at 1/1000 dilution, shown in green; Rabbit Anti-GAPDH antibody [EPR16891] (ab181602) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab300632 was shown to bind specifically to Scavenging Receptor SR-BI. A band was observed at 70 and 75 kDa in wild-type HEK-293T cell lysates with no signal observed at this size in SCARB1 knockout cell line ab282646. To generate this image, wild-type and SCARB1 knockout HEK-293T cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed (ab216772) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed (ab216777) at 1/20000 dilution.

Scavenging Receptor Class B Type 1 (SR-BI) also known as CLA-1 in humans is a membrane protein involved in the selective uptake of lipids. This protein has a molecular mass of approximately 82 kDa and is primarily expressed in the liver and non-placental tissues such as adrenal glands and ovaries. SR-BI mediates the transfer of cholesterol esters from high-density lipoprotein (HDL) to cells while playing a role in reverse cholesterol transport. Its function is essential for maintaining cholesterol homeostasis.
Biological function summary

SR-BI contributes to lipid metabolism by influencing the dynamics of cholesterol and lipid circulation within the body. It forms part of the larger HDL receptor complex which facilitates the selective uptake of lipids without internalizing the entire lipoprotein. Through this mechanism SR-BI assists cells in acquiring necessary components for membrane synthesis and hormone production.

Pathways

SR-BI integrates into the cholesterol biosynthesis pathway and the reverse cholesterol transport pathway. In these pathways SR-BI works closely with proteins like ATP-binding cassette transporter A1 (ABCA1) and lecithin-cholesterol acyltransferase (LCAT). These interactions promote the efflux and transport of cholesterol therefore playing a vital role in lipid regulation and metabolic processes.

SR-BI's malfunction can lead to cardiovascular diseases due to its role in cholesterol metabolism. Elevated levels of HDL cholesterol without functional SR-BI impair reverse cholesterol transport potentially leading to atherosclerosis. Moreover SR-BI interacts with apolipoprotein A-I (apoA-I) a major protein component of HDL impacting its efficacy and connection to coronary artery disease. Understanding SR-BI pathways and their interactions can provide insights into therapeutic strategies for treating cholesterol-related disorders.

Target data

Receptor for different ligands such as phospholipids, cholesterol ester, lipoproteins, phosphatidylserine and apoptotic cells (PubMed : 12016218, PubMed : 12519372, PubMed : 21226579). Receptor for HDL, mediating selective uptake of cholesteryl ether and HDL-dependent cholesterol efflux (PubMed : 26965621). 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 (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).. (Microbial infection) Mediates uptake of M.fortuitum, E.coli and S.aureus.. (Microbial infection) Facilitates the entry of human coronavirus SARS-CoV-2 by acting as an entry cofactor through HDL binding.
