Function

Essential component of the OST-alpha/OST-beta complex, a heterotetramer that acts as the intestinal basolateral transporter responsible for bile acid export from enterocytes into portal blood. The OST-alpha/OST-beta complex efficiently transports the major species of bile acids (taurocholate). Taurine conjugates are transported more efficiently across the basolateral membrane than glycine-conjugated bile acids.

Biological Context

Subcellular Location: Basolateral cell membrane (Multi-pass membrane protein)
Tissue Specificity: Widely expressed with a high expression in ileum. Expressed in testis, colon, liver, small intestine, kidney, ovary and adrenal gland; and at low levels in heart, lung, brain, pituitary, thyroid gland, uterus, prostate, mammary gland and fat
Disease Association: Cholestasis, progressive familial intrahepatic, 6 (PFIC6) : An autosomal recessive form of progressive cholestasis, a disorder characterized by early onset of cholestasis that progresses to hepatic fibrosis, cirrhosis, and end-stage liver disease. PFIC6 patients have elevated liver transaminases and congenital diarrhea. [The disease is caused by variants affecting the gene represented in this entry]

Protein Biology

Function

Essential component of the OST-alpha/OST-beta complex, a heterotetramer that acts as the intestinal basolateral transporter responsible for bile acid export from enterocytes into portal blood (PubMed:16317684, PubMed:41606314, PubMed:41606328). The OST-alpha/OST-beta complex efficiently transports the major species of bile acids (taurocholate) (PubMed:16317684, PubMed:41606314, PubMed:41606328). Taurine conjugates are transported more efficiently across the basolateral membrane than glycine-conjugated bile acids (By similarity). In the complex, SLC51A/OST-alpha adopts a G protein-coupled receptor fold and constitutes a bile acid recognition site (PubMed:41606314, PubMed:41606328). Can also transport steroids such as estrone 3-sulfate and dehydroepiandrosterone 3-sulfate, therefore playing a role in the enterohepatic circulation of sterols (PubMed:16317684). Able to transport eicosanoids such as prostaglandin E2 (By similarity)
