Hnf1a | Hepatocyte nuclear factor 1-alpha; Transcriptional activator that regulates the tissue specific expression of multiple genes, especially in pancreatic islet cells and in liver. Binds to the inverted palindrome 5'- GTTAATNATTAAC-3'. Activates the transcription of CYP1A2, CYP2E1 and CYP3A11. Belongs to the HNF1 homeobox family. (628 aa) | ||||
Hsd3b1 | 3 beta-hydroxysteroid dehydrogenase/Delta 5-->4-isomerase type 1; A bifunctional enzyme responsible for the oxidation and isomerization of 3beta-hydroxy-Delta(5)-steroid precursors to 3-oxo- Delta(4)-steroids, an essential step in steroid hormone biosynthesis. Specifically catalyzes the conversion of pregnenolone to progesterone, 17alpha-hydroxypregnenolone to 17alpha-hydroxyprogesterone, dehydroepiandrosterone (DHEA) to 4-androstenedione, and androstenediol to testosterone. Additionally, catalyzes the interconversion between 3beta-hydroxy and 3-oxo-5alpha-androstane steroids controlli [...] (373 aa) |
