Predicted to enable several functions, including oxidoreductase activity, acting on CH-OH group of donors; oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen, NAD(P)H as one donor, and incorporation of one atom of oxygen; and oxidoreductase activity, acting on the CH-CH group of donors, NAD or NADP as acceptor. Predicted to be involved in steroid metabolic process. Predicted to be located in cytoplasm and nucleus. Predicted to be active in cytosol. Is expressed in gut endoderm; gut epithelium; hepatic primordium; pancreas epithelium; and pancreas primordium. Human ortholog(s) of this gene implicated in 46,XY sex reversal 8; B-lymphoblastic leukemia/lymphoma; T-cell acute lymphoblastic leukemia; and leukemia. Orthologous to several human genes including AKR1C1 (aldo-keto reductase family 1 member C1); AKR1C2 (aldo-keto reductase family 1 member C2); and AKR1C3 (aldo-keto reductase family 1 member C3).
