Abstract

The ionic selectivity of the Ca2+-activated K+ channel of Aplysia neurons and of the light-dependent K+ channel of Pecten photoreceptors to metal and organic cations was studied. The selectivity sequence determined from reversal potential measurements is T1+ K+ > Rb+ > NH+4 > Cs+ > Na+, Li+ and is identical to the sequence determined previously for voltage-dependent K+ channels in a variety of tissues. Our results suggest that some physical aspect of the K+ channel is conserved in phyllogenetically different tissues and cells.
