Ommatidia dissociated from flies carrying ninaCKD in a ninaC5 background show a loss of inactivation of activated-metarhodopsin, with the time constants of final response inactivation being indistinguishable in the presence or absence of Ca[2+].
The electroretinogram response of flies carrying ninaCKD in a ninaC5 background is abnormal.
Flies carrying ninaCKD in a ninaC5 background have an abnormal electroretinogram (ERG) that is distinct from that of ninaC5 flies. Flies carrying ninaCKD in a ninaC5 background do not show retinal degeneration.
