Block of Shaker potassium channels by external calcium ions

We describe an interaction between external Ca(2+) ions and Shaker K channels that is important in the gating of the channels. The interaction was first detected as a partial block of inward K(+) current in elevated Ca(2+), beginning near −40 mV and becoming stronger at more negative voltage. Surpri...
