Gating Kinetics of Single Large-Conductance Ca(2+)-Activated K(+) Channels in High Ca(2+) Suggest a Two-Tiered Allosteric Gating Mechanism(✪)

The Ca(2+)-dependent gating mechanism of large-conductance calcium-activated K(+) (BK) channels from cultured rat skeletal muscle was examined from low (4 μM) to high (1,024 μM) intracellular concentrations of calcium (Ca(2+) (i)) using single-channel recording. Open probability (P (o)) increased wi...
