K(+)-Dependent Selectivity and External Ca(2+) Block of Shab K(+) Channels
Potassium channels allow the selective flux of K(+) excluding the smaller, and more abundant in the extracellular solution, Na(+) ions. Here we show that Shab is a typical K(+) channel that excludes Na(+) under bi-ionic, Na(o)/K(i) or Na(o)/Rb(i), conditions. However, when internal K(+) is replaced...
