AKR1C2 Works in concert with the 5-alpha/5-beta-steroid reductases to convert steroid hormones into the 3-alpha/5-alpha and 3-alpha/5-beta-tetrahydrosteroids. Catalyzes the inactivation of the most potent androgen 5-alpha-dihydrotestosterone (5-alpha-DHT) to 5-alpha-androstane-3-alpha,17-beta-diol (3-alpha-diol). Has a high bile-binding ability. Belongs to the aldo/keto reductase family. Expressed in fetal testes. Expressed in fetal and adult adrenal glands. 2 alternatively spliced human isoforms have been reported.
