    Molecular mechanisms of gating in the calcium-activated chloride channel bestrophin

    Alexandria N Miller et al.
    Cryo-EM structures of the gating cycle of bestrophin reveal the molecular underpinnings of activation and inactivation gating in this calcium-activated chloride channel and reveal a surprisingly wide pore.

    Domain–domain interactions determine the gating, permeation, pharmacology, and subunit modulation of the IKs ion channel

    Mark A Zaydman et al.
    Contrary to a generally accepted principle, the pore properties of KCNQ1 channels depend on the states of voltage-sensing domains activation; KCNE1 alters the voltage-sensing domains-pore coupling to modulate KCNQ1 channel properties.

    Irreversible temperature gating in trpv1 sheds light on channel activation

    Ana Sánchez-Moreno et al.
    Temperature-activated TRPV1 ion channels respond to increased temperatures by opening and then entering an inactivated state from which they cannot recover, suggesting that this form of irreversible gating results from partial unfolding during heat absorption.
