K⁺-dependent selectivity and external Ca²⁺ 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 by Cs⁺ (Na...
