Perturbation of the second messenger homeostasis in the dark might lead to alterations in the photoresponse of the affected cells. To probe such potential variations, we simulated photoresponses from mouse rods expressing the same amounts of GCAPs investigated in the dark following the excitation of the phototransduction cascade by flashes of increasing intensity, from dim to saturating. The resulting dynamics of suppression of the dark current in a rod of a WT mouse and the respective cases for a heterozygous WT/E111V and a homozygous E111V/E111V-GCAP1 case are reported in Fig. 3a,b, respectively.
