InnateDB Gene IDBG-633901 (OSTA)
Protein Structure
UniProt Annotation
Function Essential component of the Ost-alpha/Ost-beta complex, a heterodimer that acts as the intestinal basolateral transporter responsible for bile acid export from enterocytes into portal blood. Efficiently transports the major species of bile acids (By similarity). {ECO:0000250}.
Subcellular Localization Cell membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Endoplasmic reticulum membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Note=Transported from the endoplasmic reticulum to the plasma membrane upon interacting with SLC51B. Mainly restricted to the lateral and basal membranes of ileal enterocytes (By similarity). {ECO:0000250}.
