Predicted to enable estradiol 17-beta-dehydrogenase activity; testosterone 17-beta-dehydrogenase (NADP+) activity; and testosterone dehydrogenase (NAD+) activity. Predicted to be involved in steroid biosynthetic process. Predicted to act upstream of or within lipid metabolic process. Predicted to be located in intracellular membrane-bounded organelle. Predicted to be active in endoplasmic reticulum. Is expressed in testis. Used to study pseudohermaphroditism. Human ortholog(s) of this gene implicated in 17-beta hydroxysteroid dehydrogenase 3 deficiency and disorder of sexual development. Orthologous to human HSD17B3 (hydroxysteroid 17-beta dehydrogenase 3). [provided by Alliance of Genome Resources, Apr 2022]
