HSD17B8 Antibody / 17-beta-hydroxysteroid dehydrogenase 8

Estradiol 17 beta-dehydrogenase 8, also called 17-beta-HSD 8 and Protein Ke6, is an enzyme that in humans is encoded by the HSD17B8 gene. In mice, the Ke6 protein is a 17-beta-hydroxysteroid dehydrogenase that can regulate the concentration of biologically active estrogens and androgens. It is preferentially an oxidative enzyme and inactivates estradiol, testosterone, and dihydrotestosterone. However, the enzyme has some reductive activity and can synthesize estradiol from estrone. The protein encoded by this gene is similar to Ke6 and is a member of the short-chain dehydrogenase superfamily. An alternatively spliced transcript of this gene has been detected, but the full-length nature of this variant has not been determined.
