Organic solute transporter alpha, also known as OST-alpha, is a protein which in humans is encoded by the OSTA gene.[3][4]
Function
OST-alpha together with OST-beta is able to transport estrone sulfate, taurocholate, digoxin, and prostaglandin E2 across cell membranes.[4][5] The Ost-alpha / Ost-beta heterodimer, but not the individual subunits, stimulates sodium-independent bile acid uptake.[5] The heterodimer furthermore is essential for intestinal bile acid transport.[6]
OST-alpha and OST-alpha have high expression in the testis, colon, liver, small intestine, kidney, ovary, and adrenal gland.[4]
