Predicted to enable NAD-retinol dehydrogenase activity; protein homodimerization activity; and steroid dehydrogenase activity, acting on the CH-OH group of donors, NAD or NADP as acceptor. Predicted to be involved in retinoid metabolic process and steroid metabolic process. Located in cell body. Human ortholog(s) of this gene implicated in fundus albipunctatus and night blindness. Orthologous to human RDH5 (retinol dehydrogenase 5). [provided by Alliance of Genome Resources, Apr 2022]
