Voltage and Ca(2+) Activation of Single Large-Conductance Ca(2+)-Activated K(+) Channels Described by a Two-Tiered Allosteric Gating Mechanism
The voltage- and Ca(2+)-dependent gating mechanism of large-conductance Ca(2+)-activated K(+) (BK) channels from cultured rat skeletal muscle was studied using single-channel analysis. Channel open probability (P (o)) increased with depolarization, as determined by limiting slope measurements (11 mV...
