Ion–Ion Interactions at the Selectivity Filter: Evidence from K(+)-Dependent Modulation of Tetraethylammonium Efficacy in Kv2.1 Potassium Channels
In the Kv2.1 potassium channel, binding of K(+) to a high-affinity site associated with the selectivity filter modulates channel sensitivity to external TEA. In channels carrying Na(+) current, K(+) interacts with the TEA modulation site at concentrations ≤30 μM. In this paper, we further characteri...
