Predicted to enable carbonyl reductase (NADPH) activity and oxidoreductase activity, acting on NAD(P)H, quinone or similar compound as acceptor. Predicted to be involved in several processes, including phylloquinone catabolic process; prostaglandin catabolic process; and response to progesterone. Part of subapical complex. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; nervous system; and sensory organ. Orthologous to human CBR1 (carbonyl reductase 1).
