Protein attributes

Sequence length	323 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Active toward androgens, estrogens, and xenobiotic substrates. Also exhibits low 20 alpha-HSD activity. Shows a-stereospecificity in hydrogen transfer between cofactors and substrates (A-specific). Preferentially catalyzes the reduction of 4-androstenedione, 5-alpha-androstane-3,17-dione, androsterone and dehydroepiandrosterone to testosterone, dihydrotestosterone, 5-alpha-androstane-3-alpha,17-beta-diol and 5-androstene-3-beta,17-beta-diol, respectively. Ref.2
Subunit structure	Monomer.
Tissue specificity	Mainly found in liver. Also expressed weakly in kidney. Ref.2
Post-translational modification	Three forms are detected, probably due to post-translational modifications.
Sequence similarities	Belongs to the aldo/keto reductase family.
