    The neuronal calcium sensor NCS-1 regulates the phosphorylation state and activity of the Gα chaperone and GEF Ric-8A

    Daniel Muñoz-Reyes, Levi J McClelland ... Maria Jose Sanchez-Barrena
    Biochemical, biophysical, and structural approach to determine the molecular basis of the calcium-sensitive regulation of the Gα chaperone and guanine exchange factor Ric-8A by the neuronal calcium sensor NCS-1.

    Apolipoprotein L-1 renal risk variants form active channels at the plasma membrane driving cytotoxicity

    Joseph A Giovinazzo, Russell P Thomson ... Ryan Schreiner
    Cytotoxicity associated with APOL1 renal-risk variants occurs through its plasma-membrane localization, where aberrant channel activity drives a sustained sodium and calcium influx leading to cell swelling and eventually cell death.

    Enhanced excitability of cortical neurons in low-divalent solutions is primarily mediated by altered voltage-dependence of voltage-gated sodium channels

    Briana J Martiszus, Timur Tsintsadze ... Stephen M Smith
    External calcium regulates neuronal excitability via its actions on voltage-gated sodium channels but not by regulating NALCN via the calcium-sensing receptor.

    Distinct gating mechanisms revealed by the structures of a multi-ligand gated K+ channel

    Chunguang Kong, Weizhong Zeng ... Youxing Jiang
    Structural and functional studies of a potassium ion channel that is opened and closed by different ligands have revealed a novel gating mechanism.

    Lipids and ions traverse the membrane by the same physical pathway in the nhTMEM16 scramblase

    Tao Jiang, Kuai Yu ... Emad Tajkhorshid
    A concerted approach employing equilibrium and biased molecular simulations, electrophysiology, mutagenesis, and functional assays reveals, in atomic details, the mechanism and pathway for transport of phospholipids and ions by a lipid scramblase.

    Agonist-mediated switching of ion selectivity in TPC2 differentially promotes lysosomal function

    Susanne Gerndt, Cheng-Chang Chen ... Christian Grimm
    The lysosomal ion channel TPC2 emerges as an example of an ion channel in which ion selectivity is not fixed but rather agonist-selective.

    The Ca2+ transient as a feedback sensor controlling cardiomyocyte ionic conductances in mouse populations

    Colin M Rees, Jun-Hai Yang ... Alain Karma
    Feedback sensing of the intracellular calcium concentration suffices to reproduce the diversity of ionic conductances underlying normal cardiac electromechanical function in a genetically diverse population of mice.

    Polyunsaturated fatty acid analogues differentially affect cardiac NaV, CaV, and KV channels through unique mechanisms

    Briana M Bohannon, Alicia de la Cruz ... H Peter Larsson
    Polyunsaturated fatty acid analogues show selectivity for different cardiac ion channels, suggesting their potential use for the treatment of different subtypes of Long QT Syndrome.

    Glial Ca2+signaling links endocytosis to K+ buffering around neuronal somas to regulate excitability

    Shirley Weiss, Jan E Melom ... J Troy Littleton
    An unbiased genetic screen in Drosophila provides evidence for a direct link between glial Ca2+ 25 signaling and classical functions of glia in buffering external K+ as a mechanism to regulate neuronal excitability.
