[https://www.uniprot.org/uniprot/AK1C1_HUMAN AK1C1_HUMAN] Converts progesterone to its inactive form, 20-alpha-dihydroxyprogesterone (20-alpha-OHP). In the liver and intestine, may have a role in the transport of bile. May have a role in monitoring the intrahepatic bile acid concentration. Has a low bile-binding ability. May play a role in myelin formation.<ref>PMID:11013348</ref> <ref>PMID:8573067</ref>
