UniProtKB description:  NADPH-dependent oxidoreductase which catalyzes the reduction of a variety of compounds bearing carbonyl groups including ketosteroids, alpha-dicarbonyl compounds, aldehydes, aromatic ketones and quinones (PubMed:12604222, PubMed:19056333). Reduces all-trans-retinal and 9-cis retinal (Probable). Reduces 3-ketosteroids and benzil into 3alpha-hydroxysteroids and S-benzoin, respectively, in contrast to the stereoselectivity of primates DHRS4s which produce 3beta-hydroxysteroids and R-benzoin (PubMed:19056333). In the reverse reaction, catalyzes the NADP-dependent oxidation of 3alpha-hydroxysteroids and alcohol, but with much lower efficiency (PubMed:19056333). Involved in the metabolism of 3alpha-hydroxysteroids, retinoid, isatin and xenobiotic carbonyl compounds (PubMed:12604222, PubMed:19056333).
