Background
This gene encodes a member of the aldo/keto reductase superfamily, which consists of more than 40 known enzymes and proteins. These enzymes catalyze the conversion of aldehydes and ketones to their corresponding alcohols by utilizing NADH and/or NADPH as cofactors. The enzymes display overlapping but distinct substrate specificity. This enzyme catalyzes the reaction of progesterone to the inactive form 20-alpha-hydroxy-progesterone. This gene shares high sequence identity with three other gene members and is clustered with those three genes at chromosome 10p15-p14. [provided by RefSeq, Jul 2008],
Function
catalytic activity:17-alpha,20-alpha-dihydroxypregn-4-en-3-one + NAD(P)(+) = 17-alpha-hydroxyprogesterone + NAD(P)H.,catalytic activity:Indan-1-ol + NAD(P)(+) = indanone + NAD(P)H.,catalytic activity:Trans-1,2-dihydrobenzene-1,2-diol + NADP(+) = catechol + NADPH.,enzyme regulation:Inhibited by hexestrol with an IC(50) of 9.5 uM, 1,10-phenanthroline with an IC(50) of 55 uM, 1,7-phenanthroline with an IC(50) of 72 uM, flufenamic acid with an IC(50) of 6.0 uM, indomethacin with an IC(50) of 140 uM, ibuprofen with an IC(50) of 950 uM, lithocholic acid with an IC(50) of 25 uM, ursodeoxycholic acid with an IC(50) of 340 uM and chenodeoxycholic acid with an IC(50) of 570 uM.,function: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 a
