Shifts in the selectivity filter dynamics cause modal gating in K+ channels

Spontaneous activity shifts at constant experimental conditions are widespread among ion channels but the molecular origins are poorly understood. Here, using solid-state NMR and MD simulations, the authors reveal that modal gating shifts in K + channels are caused by large shifts in the channel dyn...

Sumario:Spontaneous activity shifts at constant experimental conditions are widespread among ion channels but the molecular origins are poorly understood. Here, using solid-state NMR and MD simulations, the authors reveal that modal gating shifts in K + channels are caused by large shifts in the channel dynamics which perturb the selectivity filter.
