17β-Hydroxysteroid dehydrogenase type 14 also known as 17β-HSD type 14 or 17βHSD14 is an enzyme that in humans is encoded by the HSD17B14gene.[5][6]
17βHSD14 catalyzes the stereospecific oxidation and reduction of the 17β carbon atom of androgens and estrogens using NAD(P)(H) as a cofactor. It is primarily expressed in glandular epithelial tissues of breast, ovary, and testis.[7]
