Organic solute transporter alpha, also known as OST-alpha, is a protein which in humans is encoded by the SLC51A gene.[5][6]

Function

OST-alpha together with OST-beta is able to transport estrone sulfate, taurocholate, digoxin, and prostaglandin E2 across cell membranes.[6][7] The Ost-alpha / Ost-beta heterodimer, but not the individual subunits, stimulates sodium-independent bile acid uptake.[7] The heterodimer furthermore is essential for intestinal bile acid transport.[8]

OST-alpha and OST-alpha have high expression in the testis, colon, liver, small intestine, kidney, ovary, and adrenal gland.[6]
