Summary
The protein encoded by this gene has both oxidoreductase and epimerase activities and is involved in androgen catabolism. The oxidoreductase activity can convert 3 alpha-adiol to dihydrotestosterone, while the epimerase activity can convert androsterone to epi-androsterone. Both reactions use NAD+ as the preferred cofactor. This gene is a member of the retinol dehydrogenase family. [provided by RefSeq, Aug 2013]

Comments

Comment Type Description
Biophysicochemical Properties Kinetic parameters: KM=0.19 uM for NAD {ECO
Catalytic Activity 17-beta-estradiol + NAD(P)(+) = estrone + NAD(P)H.
Catalytic Activity All-trans-retinol-[cellular-retinol-binding- protein] + NAD(+) = all-trans-retinal-[cellular-retinol-binding- protein] + NADH.
Catalytic Activity Testosterone + NAD(+) = androstenedione + NADH.
Function NAD-dependent oxidoreductase with broad substrate specificity that shows both oxidative and reductive activity (in vitro). Has 17-beta-hydroxysteroid dehydrogenase activity towards various steroids (in vitro). Converts 5-alpha-androstan-3- alpha,17-beta-diol to androsterone and estradiol to estrone (in vitro). Has 3-alpha-hydroxysteroid dehydrogenase activity towards androsterone (in vitro). Has retinol dehydrogenase activity towards all-trans-retinol (in vitro). Can convert androsterone to epi-androsterone. Androsterone is first oxidized to 5-alpha- androstane-3,17-dione and then reduced to epi-andosterone. Can act on both C-19 and C-21 3-alpha-hydroxysteroids. {ECO
Sequence Caution Sequence=AAB88252.1; Type=Frameshift; Positions=158, 174; Evidence= ;
Similarity Belongs to the short-chain dehydrogenases/reductases (SDR) family.
Subcellular Location Microsome membrane ; Peripheral membrane protein ; Lumenal side . Early endosome membrane {ECO
Tissue Specificity Detected in liver and prostate (at protein level). Detected in adult liver, lung, brain, placenta, prostate, adrenal gland, testis, mammary gland, spleen, spinal cord and uterus. Detected in caudate nucleus, and at lower levels in amygdala, corpus callosum, hippocampus, substantia nigra and thalamus. Detected in fetal lung, liver and brain.
