**Background of SCARB1 Recombinant Protein**
SCARB1 (Scavenger Receptor Class B Type 1), also known as SR-BI, is a cell surface glycoprotein belonging to the scavenger receptor family. It plays a critical role in cholesterol metabolism by facilitating the bidirectional transfer of cholesteryl esters between high-density lipoprotein (HDL) particles and cells. SCARB1 is highly expressed in tissues involved in lipid regulation, including the liver, adrenal glands, and macrophages. Its function in mediating selective HDL cholesterol uptake makes it a key player in reverse cholesterol transport, a process critical for reducing atherosclerosis risk.
Structurally, SCARB1 contains two extracellular domains, a transmembrane domain, and a short cytoplasmic tail. Its extracellular region interacts with lipoprotein particles, while the cytoplasmic domain participates in intracellular signaling. SCARB1 also exhibits non-lipid-related roles, such as modulating inflammation, apoptosis, and pathogen entry (e.g., hepatitis C virus).
Recombinant SCARB1 protein is produced using expression systems like mammalian cells or *E. coli*, enabling studies of its structure-function relationships, ligand interactions, and regulatory mechanisms. Purified recombinant SCARB1 is widely used in biochemical assays, drug discovery (e.g., HDL-targeted therapies), and investigating diseases linked to lipid dysregulation, such as cardiovascular disorders and metabolic syndrome. Additionally, it serves as a tool to explore SCARB1’s involvement in viral infections or cancer progression.
Research on SCARB1 recombinant protein has advanced understanding of its dual roles in lipid metabolism and cellular signaling, highlighting its potential as a therapeutic target for atherosclerosis, obesity, and infectious diseases.
