This second of three papers, in which we functionally characterize activation gating in Shaker potassium channels, focuses on the properties of a mutant channel (called V2), in which the leucine at position 382 (in the Shaker B sequence) is mutated to valine. The general properties of V2's ionic and gating currents are consistent with changes ...

Calculations for the Modeling. For the modeling of Shaker's activation gating, we assume continuous-time, discrete-state Markov models, which have performed adequately at describing the gating processes of many other ion channels (for example, see McManus and Magleby, 1988).For all of the calculations, the numerical techniques described by Colquhoun …

Shaker Tables and Vibrating Screens. Shaker tables and vibrating screens separate granule sizes by vibrating the materials through a sifting screen or by shaking them on a specially-designed table that used the density and specific gravity of the raw material to sort it. We employ many other machines that are designed for specific tasks.

For instance, Q-V curves of Shaker potassium channel obtained by hyperpolarizing from 0 mV is left-shifted compared to those obtained by depolarizing from a holding potential of −80 mV. This hysteresis in Q-V curves is a common feature of channels in the VGIC superfamily and raises profound questions about channel energetics because the net ...
