A synthetic peptide corresponding to a sequence at the N-terminus of human HSD17B1, different from the related rat and mouse sequences by one amino acid.
HSD17B1(17-BETA-HYDROXYSTEROID DEHYDROGENASE I), also known as 17-beta-hydroxysteroid dehydrogenase or 17-ketosteroid reductase, is an enzyme that is responsible for the interconversion of estrone (E1) and estradiol (E2) as well as the interconversion of androstenedione and testosterone. Its cytogenetic location is 17q21.2. HSD17B1 gene expression is detected in 34 of 42 (81%) adenomas in all tumor subtypes, HSD17B2 mRNA is detected in 18 of 42 (43%) adenomas but not in prolactinomas. Human estrogenic HSD17B1 is an NADP(H)-preferring enzyme. It possesses 11- and 4-fold higher specificity toward NADP(H) over NAD(H) for oxidation and reduction, respectively, as demonstrated by kinetic studies. All 4 HSD17B isoforms are variably expressed in human anterior pituitary adenomas, which also show HSD17B enzyme activity, suggesting that HSD17B may play an important role in regulating the local cellular levels of estradiol. UniProt Number: P14061 Gene ID: HSD17B1 Applications: Suitable for use in Western Blot, Immunohistochemistry (Paraffin) and Immunocytochemistry.
