3 beta-hydroxysteroid dehydrogenase (3beta-HSD), also known as HSD3B1 or HSDB3, is a bifunctional enzyme that plays a crucial role in the synthesis of all classes of hormonal steroids. Two human 3beta-HSD proteins, designated type I (3beta-HSD) and type II (3beta-HSD2), are expressed by different genes and function in different areas of the body. Localized to the membrane of the endoplasmic reticulum (ER) and expressed in skin and placenta, 3beta-HSD is the type I protein that catalyzes the oxidative conversion of delta5-ene-3-beta-hydroxy steroid, as well as the conversion of various ketosteroids. Defects in the gene encoding 3beta-HSD are associated with classic salt wasting, genital ambiguity, hypogonadism, insulin-resistant polycystic ovary syndrome (PCOS) and an increased susceptibility to prostate cancer. Additionally, congenital deficiency of 3beta-HSD activity results in a severe depletion of steroid formation which can be lethal in young children.
