== Disease ==
[https://www.uniprot.org/uniprot/OSTA_HUMAN OSTA_HUMAN] The disease is caused by variants affecting the gene represented in this entry.
== Function ==
[https://www.uniprot.org/uniprot/OSTA_HUMAN OSTA_HUMAN] 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 (PubMed:16317684). Efficiently transports the major species of bile acids (taurocholate) (PubMed:16317684). Taurine conjugates are transported more efficiently across the basolateral membrane than glycine-conjugated bile acids (By similarity). 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).[UniProtKB:Q8R000][UniProtKB:Q90YM5]<ref>PMID:16317684</ref>
