Coupling between Voltage Sensor Activation, Ca(2+) Binding and Channel Opening in Large Conductance (BK) Potassium Channels

To determine how intracellular Ca(2+) and membrane voltage regulate the gating of large conductance Ca(2+)-activated K(+) (BK) channels, we examined the steady-state and kinetic properties of mSlo1 ionic and gating currents in the presence and absence of Ca(2+) over a wide range of voltage. The acti...
