Anti-17-beta-HSD 3 / HSD17B3

0.5mg/ml if reconstituted with 0.2ml sterile DI water. 17beta-Hydroxysteroid dehydrogenase 3 (17b-HSD3) is an enzyme that in humans is encoded by the HSD17B3 gene and is involved in androgen steroidogenesis. This isoform of 17 beta-hydroxysteroid dehydrogenase is expressed predominantly in the testis and catalyzes the conversion of androstenedione to testosterone. It preferentially uses NADP as cofactor. Deficiency can result in male pseudohermaphroditism with gynecomastia. Protein function: Catalyzes the conversion of 17-oxosteroids to 17beta- hydroxysteroids (PubMed:8075637, PubMed:16216911, PubMed:27927697, PubMed:26545797). Favors the reduction of androstenedione to testosterone (PubMed:16216911, PubMed:27927697, PubMed:26545797). Testosterone is the key androgen driving male development and function (PubMed:8075637). Uses NADPH while the two other EDH17B enzymes use NADH (PubMed:26545797, PubMed:8075637, PubMed:16216911). Androgens such as epiandrosterone, dehydroepiandrosterone, androsterone and androstanedione are accepted as substrates and reduced at C-17 (PubMed:16216911). Can reduce 11-ketoandrostenedione as well as 11beta- hydroxyandrostenedione at C-17 to the respective testosterone forms (PubMed:16216911, PubMed:27927697). [The UniProt Consortium]
