Voltage-dependence of Ion Permeation in Cyclic GMP–gated Ion Channels Is Optimized for Cell Function in Rod and Cone Photoreceptors

The kinetics of the photocurrent in both rod and cone retinal photoreceptors are independent of membrane voltage over the physiological range (−30 to −65 mV). This is surprising since the photocurrent time course is regulated by the influx of Ca(2+) through cGMP-gated ion channels (CNG) and the forc...
