Gene: HSD3B1 (hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 1) Homo sapiens
Symbol: HSD3B1
Name: hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 1
Description: Predicted to have 3-beta-hydroxy-delta5-steroid dehydrogenase activity and steroid delta-isomerase activity. Predicted to be involved in several processes, including C21-steroid hormone metabolic process; hippocampus development; and response to corticosterone. Localizes to several cellular components, including intercellular bridge; mitochondrial envelope; and nucleolus. Implicated in hypertension.
Type: protein-coding
RefSeq Status: REVIEWED
