Divalent Cation Interactions with Light-Dependent K Channels: Kinetics of Voltage-Dependent Block and Requirement for an Open Pore
The light-dependent K conductance of hyperpolarizing Pecten photoreceptors exhibits a pronounced outward rectification that is eliminated by removal of extracellular divalent cations. The voltage-dependent block by Ca(2+) and Mg(2+) that underlies such nonlinearity was investigated. Both divalents r...
