HSE, or Hydroxysteroid (17-beta) dehydrogenase 6, is a human gene encoded by HSD17B6. It may also be known as: 17-beta-hydroxysteroid dehydrogenase type 6; 17-beta-HSD 6; 17-beta-HSD6; 3-alpha->beta-hydroxysteroid epimerase; 3-alpha->beta-HSE; Oxidative 3-alpha hydroxysteroid dehydrogenase; Short chain dehydrogenase/reductase family 9C member 6; oxidative 3-alpha-hydroxysteroid-dehydrogenase; 3(alpha->beta)-hydroxysteroid epimerasel; oxidoreductase; NAD+ -dependent 3 alpha-hydroxysteroid dehydrogenase; 3-hydroxysteroid epimerase; short chain dehydrogenase/reductase family 9C, member 6; RODH; SDR9C6. The encoded protein is an enzyme with an amino acid length of 317 and a mass of 36.0 kDa. Other isoforms may exist. HSE is a member of the Short-chain dehydrogenases/reductases (SDR) family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Frog.
