Enables NAD-retinol dehydrogenase activity and alcohol dehydrogenase (NAD+) activity. Acts upstream of or within ethanol catabolic process; retinoic acid metabolic process; and retinol metabolic process. Predicted to be located in plasma membrane. Predicted to be active in cytosol. Is expressed in several structures, including branchial arch; embryo mesenchyme; endocrine gland; neural fold; and reproductive system. Used to study Parkinson's disease. Orthologous to human ADH7 (alcohol dehydrogenase 7 (class IV), mu or sigma polypeptide). [provided by Alliance of Genome Resources, Apr 2022]
