Hsd3b4 - hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 4

Predicted to enable 3-beta-hydroxy-delta5-steroid dehydrogenase activity; steroid binding activity; and steroid delta-isomerase activity. Acts upstream of or within response to stilbenoid. Located in mitochondrial inner membrane. Is expressed in several structures, including alimentary system; eye; heart; nervous system; and urinary system. Human ortholog(s) of this gene implicated in hypertension and hypospadias. Orthologous to human HSD3B1 (hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 1) and HSD3B2 (hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 2).
