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. Defects in AKR1C2 are a cause of 46,XY sex reversal type 8 (SRXY8). A disorder of sex development. Affected individuals have a 46,XY karyotype but present as phenotypically normal females. Belongs to the aldo/keto reductase family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: EC 188.8.131.527; EC 184.108.40.206; Oxidoreductase; Xenobiotic Metabolism - metabolism by cytochrome P450
