CC -!- FUNCTION: Cytosolic aldo-keto reductase that catalyzes the NADH and
CC NADPH-dependent reduction of ketosteroids to hydroxysteroids. Acts as a
CC NAD(P)(H)-dependent 3-, 17- and 20-ketosteroid reductase on the steroid
CC nucleus and side chain and regulates the metabolism of androgens,
CC estrogens and progesterone (PubMed:10622721, PubMed:11165022,
CC PubMed:7650035, PubMed:9415401, PubMed:9927279). Displays the ability
CC to catalyze both oxidation and reduction in vitro, but most probably
CC acts as a reductase in vivo since the oxidase activity measured in
CC vitro is inhibited by physiological concentration of NADPH
CC (PubMed:14672942, PubMed:11165022). Acts preferentially as a 17-
CC ketosteroid reductase and has the highest catalytic efficiency of the
CC AKR1C enzyme for the reduction of delta4-androstenedione to form
CC testosterone (PubMed:20036328). Reduces prostaglandin (PG) D2 to
CC 11beta-prostaglandin F2, progesterone to 20alpha-hydroxyprogesterone
CC and estrone to 17beta-estradiol (PubMed:15047184, PubMed:20036328,
CC PubMed:10622721, PubMed:11165022, PubMed:10998348, PubMed:19010934).
CC Catalyzes the transformation of the potent androgen dihydrotestosterone
CC (DHT) into the less active form, 5-alpha-androstan-3-alpha,17-beta-diol
CC (3-alpha-diol) (PubMed:10998348, PubMed:14672942, PubMed:11165022,
CC PubMed:7650035, PubMed:9415401, PubMed:10557352). Also displays
CC retinaldehyde reductase activity toward 9-cis-retinal
CC (PubMed:21851338). {ECO:0000269|PubMed:10557352,
