Enables NAD-retinol dehydrogenase activity and identical protein binding activity. Involved in retinoid metabolic process and steroid metabolic process. Acts upstream of or within 9-cis-retinoic acid biosynthetic process. Located in endoplasmic reticulum lumen and endoplasmic reticulum membrane. Is integral component of organelle membrane. Is expressed in alimentary system; embryo; future spinal cord; liver; and salivary gland. Orthologous to human RDH16 (retinol dehydrogenase 16). [provided by Alliance of Genome Resources, Apr 2022]
