Divalent Cation Selectivity Is a Function of Gating in Native and Recombinant Cyclic Nucleotide–gated Ion Channels from Retinal Photoreceptors
The selectivity of Ca(2+) over Na(+) is ∼3.3-fold larger in cGMP-gated channels of cone photoreceptors than in those of rods when measured under saturating cGMP concentrations, where the probability of channel opening is 85–90%. Under physiological conditions, however, the probability of opening of...
