Protein Structure

UniProt Annotation

Function

The 3-beta-HSD enzymatic system plays a crucial role in the biosynthesis of all classes of hormonal steroids. HSD V can only catalyze the conversion of dihydrotestosterone to 5 alpha- androstanediol in the presence of the cofactor NADPH. Does not function as a isomerase.

Subcellular Localization

Endoplasmic reticulum membrane; Single-pass membrane protein. Mitochondrion membrane; Single-pass membrane protein.

Disease Associations

Tissue Specificity

Expressed in the male liver, starting in late puberty.
