Localization of the K(+) Lock-in and the Ba(2+) Binding Sites in a Voltage-Gated Calcium-Modulated Channel: Implications for Survival of K(+) Permeability

Using Ba(2+) as a probe, we performed a detailed characterization of an external K(+) binding site located in the pore of a large conductance Ca(2+)-activated K(+) (BK(Ca)) channel from skeletal muscle incorporated into planar lipid bilayers. Internal Ba(2+) blocks BK(Ca) channels and decreasing ext...
