    Piezo’s membrane footprint and its contribution to mechanosensitivity

    Christoph A Haselwandter, Roderick MacKinnon
    Membrane mechanics predict that the ion channel Piezo recruits the surrounding membrane to amplify its sensitivity to changes in membrane tension, with greatest sensitivity in the low-tension regime.

    Identification of a lipid scrambling domain in ANO6/TMEM16F

    Kuai Yu et al.
    The amino acids that are necessary for phospholipid scrambling by ANO6/TMEM16F can, via domain swapping, confer scrambling activity to the chloride ion channel ANO1 that normally does not scramble phospholipids.

    Phosphatidic acid modulation of Kv channel voltage sensor function

    Richard K Hite et al.
    Phosphatidic acid influences the gating of voltage-gated K+ channels through a non-specific surface charge mechanism and through a specific interaction between a voltage sensor arginine and the primary phosphate head group on the cytoplasmic membrane leaflet.

    A label-free approach to detect ligand binding to cell surface proteins in real time

    Verena Burtscher et al.
    Binding of a charged small molecule to a membrane protein changes the amplitude of the apparent membrane capacitance by changing the charge density at the surfaces of the membrane.

    Sculpting ion channel functional expression with engineered ubiquitin ligases

    Scott A Kanner et al.
    Engineered E3 ubiquitin ligases are utilized to elucidate mechanisms underlying ubiquitin regulation of membrane proteins, and to achieve robust post-translational functional knockdown of ion channels.

    The Ca2+-activated K+ current of human sperm is mediated by Slo3

    Christoph Brenker et al.
    The principal potassium ion channel in human sperm, Slo3, is primarily activated by calcium ions and controls the membrane potential of human sperm by intracellular calcium ion levels rather than intracellular pH.

    Cation selectivity of the presequence translocase channel Tim23 is crucial for efficient protein import

    Niels Denkert et al.
    Channel characteristics of the presequence translocation pore have a direct impact on protein import into the mitochondrial matrix.

    A family of fluoride-specific ion channels with dual-topology architecture

    Randy B Stockbridge et al.
    Efflux of xenobiotic fluoride from microorganisms occurs through a novel family of ion channels with stringent selectivity for fluoride ion and dual-topology molecular architecture.

    Structure of a TRPM2 channel in complex with Ca2+ explains unique gating regulation

    Zhe Zhang et al.
    The 3Å structure and correlated functional analysis of the TRPM2 cation channel from Nematostella vectensis shed light on the molecular mechanisms of TRPM2 regulation by intra- and extracellular Ca2+, and of inactivation of human TRPM2.

    Structural basis of Ca2+-dependent activation and lipid transport by a TMEM16 scramblase

    Maria E Falzone et al.
    Structures of a TMEM16 phospholipid scramblase reveal that its Ca2+-dependent activation entails global conformational changes and how these rearrangements affect the membrane to enable transbilayer lipid transfer.
