Enables androsterone dehydrogenase activity. Predicted to be involved in glycoside metabolic process; progesterone metabolic process; and prostaglandin metabolic process. Predicted to be located in cytoplasm and nucleus. Predicted to be active in cytosol. Is expressed in gut; liver; metanephros; reproductive system; and respiratory system. 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).
