    Helix breaking transition in the S4 of HCN channel is critical for hyperpolarization-dependent gating

    Marina A Kasimova et al.
    The gating polarity of a voltage-gated ion channel is primarily determined by turn propensity of residues at a critical position in the middle of the S4 voltage-sensing helix.

    Structure and dynamics underlying elementary ligand binding events in human pacemaking channels

    Marcel P Goldschen-Ohm et al.
    Single-molecule resolution of cAMP binding to the ligand binding domain of pacemaking channels in zero-mode waveguides reveals the dynamics of the distinct steps underlying both binding and isomerization of the binding domain.

    Activation of the archaeal ion channel MthK is exquisitely regulated by temperature

    Yihao Jiang et al.
    Temperature-sensitivity of archaebacterial potassium channel MthK is regulated by RCK domain via alteration of allosteric coupling.

    Top-down machine learning approach for high-throughput single-molecule analysis

    David S White et al.
    A new analysis algorithm (DISC) enables accurate analysis of data from high-throughput single-molecule paradigms and reveals a non-cooperative binding mechanism of cyclic nucleotide-binding domains from HCN ion channels.

    A selectivity filter at the intracellular end of the acid-sensing ion channel pore

    Timothy Lynagh et al.
    Sodium selectivity of acid-sensing ion channels is mediated by negatively charged side chains and not by a size-exclusion mechanism.

    Sequential phenotypic constraints on social information use in wild baboons

    Alecia J Carter et al.
    Social information is a process encompassing information acquisition, application and exploitation that is constrained by an individual’s social, behavioural and demographic phenotype.

    Real time dynamics of Gating-Related conformational changes in CorA

    Martina Rangl et al.
    High-speed atomic force microscopy reveals that the open state of the divalent ion channel CorA is highly dynamic and defined by the fast exchange between conformations.

    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.

    ATP and large signaling metabolites flux through caspase-activated Pannexin 1 channels

    Adishesh K Narahari et al.
    Purified Pannexin 1 channels activated by caspase cleavage in proteoliposomes reconstitute a permeation pathway for intercellular signaling molecules important in inflammation and cell clearance.

    Molecular mechanisms of human P2X3 receptor channel activation and modulation by divalent cation bound ATP

    Mufeng Li et al.
    Structural, computational and functional approaches reveal the role of an extended acidic chamber near the nucleotide binding site in activation of P2X3 receptor channels by divalent-bound ATP.
