catalytic activity:1,5-anhydro-D-glucitol + NADP(+) = 1,5-anhydro-D-fructose + NADPH.,function:Catalyzes the NADPH-dependent reduction of 1,5-anhydro-D-fructose (AF) to 1,5-anhydro-D-glucitol. Can also catalyze the reduction of various aldehydes and quinones.,similarity:Belongs to the aldo/keto reductase family.,tissue specificity:Testis-specific.,
