Background Information

Organic solute transporter alpha-beta (Ostα-Ostβ) is a heteromeric transporter that has been localized to the basolateral membrane of epithelial cells of the small intestine, kidney and liver, and appears to be essential for bile acid homeostasis. The transporter is composed of a predicted 340-amino acid, 7-transmembrane domain protein (Ostα) and a putative 128-amino acid, single-transmembrane domain polypeptide (Ostβ). Ostα-Ostβ transports bile acids by a facilitated diffusion mechanism; therefore, Ostα-Ostβ can mediate cellular efflux or uptake depending on the substrate's electrochemical gradient. It's reported that Ostα-Ostβ is not only essential for bile acid, but also vital for sterol disposition and enterohepatic circulation(PMID: 21691099).
