Summaries for HSD17B8 Gene

Entrez Gene Summary for 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. [provided by RefSeq, Jul 2008]

GeneCards Summary for HSD17B8 Gene

HSD17B8 (Hydroxysteroid 17-Beta Dehydrogenase 8) is a Protein Coding gene. Among its related pathways are Estrone metabolism and Metabolism. GO annotations related to this gene include oxidoreductase activity and 3-hydroxyacyl-CoA dehydrogenase activity. An important paralog of this gene is CBR4.

UniProtKB/Swiss-Prot for HSD17B8 Gene

  • NAD-dependent 17-beta-hydroxysteroid dehydrogenase with highest activity towards estradiol. Has very low activity towards testosterone. The heterotetramer with CBR4 has NADH-dependent 3-ketoacyl-acyl carrier protein reductase activity. May play a role in biosynthesis of fatty acids in mitochondria.
