Crystal Structure of Human Type III 3-alpha-Hydroxysteroid Dehydrogenase/Bile Acid Binding Protein (AKR1C2) Complexed with NADP+ and Ursodeoxycholate
Template:ABSTRACT PUBMED 11513593
Disease
[AK1C2_HUMAN] Defects in AKR1C2 are a cause of 46,XY sex reversal type 8 (SRXY8) [MIM:614279]. A disorder of sex development. Affected individuals have a 46,XY karyotype but present as phenotypically normal females.[1]
Function
[AK1C2_HUMAN] 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.[2]
