    Slo2 potassium channel function depends on RNA editing-regulated expression of a SCYL1 protein

    Long-Gang Niu et al.
    The pseudokinase protein SCYL1 is an evolutionarily conserved enhancer of Slo2 potassium channel activity.

    Atomic mutagenesis in ion channels with engineered stoichiometry

    John D Lueck et al.
    Building on previous work (Pless, 2013), we argue that side-chain 'flip out' is a key event in potassium channel C-type inactivation, and propose a new method for encoding multiple noncanonical amino acids and controlling protein stoichiometry.

    Structure of a pore-blocking toxin in complex with a eukaryotic voltage-dependent K+ channel

    Anirban Banerjee et al.
    Charybdotoxin, a toxin produced by scorpions, blocks a K+ channel by binding in a lock-and-key fashion to the mouth of the channel and presenting a lysine amino group, which serves as a K+ mimic in the selectivity filter.

    Single-particle cryo-EM structure of a voltage-activated potassium channel in lipid nanodiscs

    Doreen Matthies et al.
    The structure of a voltage-activated potassium channel in lipid nanodiscs solved using cryo-electron microscopy is similar to previous X-ray structures, and provides insights into the mechanism of C-type inactivation.

    Trans-toxin ion-sensitivity of charybdotoxin-blocked potassium-channels reveals unbinding transitional states

    Hans Moldenhauer et al.
    Detection of unbinding transitional states in the charybdotoxin first-order dissociation from a Kv-channel reveals that the bound neurotoxin wobbles, suggesting diverse intermediates and dissociation pathways in this protein–protein interaction.

    The palmitoyl acyltransferase ZDHHC14 controls Kv1-family potassium channel clustering at the axon initial segment

    Shaun S Sanders et al.
    ZDHHC14 controls palmitoylation and axon initial segment targeting of PSD93 and Kv1-family potassium channels, events that are essential for normal neuronal excitability.

    Gi/o protein-coupled receptors in dopamine neurons inhibit the sodium leak channel NALCN

    Fabian Philippart, Zayd M Khaliq
    The sodium leak NALCN channel functions as a core effector of GABA-B and D2 receptors that is used along with GIRK channels to regulate action potential firing in dopamine neurons.

    Computational models of O-LM cells are recruited by low or high theta frequency inputs depending on h-channel distributions

    Vladislav Sekulić, Frances K Skinner
    The contribution of biophysical ion channels to neuron function can be predicted by taking advantage of an ongoing dialogue between model and experiment.

    Potassium dependent rescue of a myopathy with core-like structures in mouse

    M Gartz Hanson et al.
    A mouse model of human muscle myopathy is used to provide mechanistic insight, identify possible biomarkers of disease, and suggest possible therapeutic strategies to alleviate muscle weakness.

    Stochastic and deterministic dynamics of intrinsically irregular firing in cortical inhibitory interneurons

    Philipe RF Mendonça et al.
    A-type potassium conductances influence the distinctive firing behaviour of irregular-spiking interneurons.
