    The neuronal calcium sensor Synaptotagmin-1 and SNARE proteins cooperate to dilate fusion pores

    Zhenyong Wu et al.
    During neurotransmitter release, calcium-induced membrane insertion of the C2B domain of Synaptotagmin re-orients the bound SNARE complex which dilates the fusion pore in a mechanical lever action.

    Clusters of cooperative ion channels enable a membrane-potential-based mechanism for short-term memory

    Paul Pfeiffer et al.
    Independently gating ion channels typically act fast within milliseconds, but cooperative interactions within a cluster of channels allow for a memory of previous electrical activity for several seconds.

    Site-directed MT1-MMP trafficking and surface insertion regulate AChR clustering and remodeling at developing NMJs

    Zora Chui-Kuen Chan et al.
    Postsynaptic MT1-MMP serves as a molecular switch to synaptogenesis by clearing the surrounding ECM environment that allows effective deposition of nerve-derived synaptogenic factors to induce postsynaptic differentiation at developing NMJs.

    HCN channel-mediated neuromodulation can control action potential velocity and fidelity in central axons

    Niklas Byczkowicz et al.
    The cAMP-HCN pathway can control action potential conduction velocity providing neuromodulators with the ability to tune energy consumption and temporal delays across axons in the brain.

    Spatially compartmentalized phase regulation of a Ca2+-cAMP-PKA oscillatory circuit

    Brian Tenner et al.
    Nanodomain clustering of cAMP effectors represents a novel mechanism of cAMP compartmentation within an oscillatory signaling circuit.

    A physical mechanism of TANGO1-mediated bulky cargo export

    Ishier Raote et al.
    TANGO1 functions as a linactant filament to stabilize shallow COPII-coated buds, and after which membrane tension regulation, possibly mediated by TANGO1-controlled membrane fusion, facilitates bud elongation for procollagen export.

    Mechanics and dynamics of translocating MreB filaments on curved membranes

    Felix Wong et al.
    Principal curvature-dependent motion of bacterial actin MreB results in localization consistent with all known literature.

    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.

    Dynamic clustering of dynamin-amphiphysin helices regulates membrane constriction and fission coupled with GTP hydrolysis

    Tetsuya Takeda et al.
    A new approach using combination of electron microscopy (EM) and high-speed atomic force microscopy (HS-AFM) clearly demonstrates dynamics of dynamin-amphiphysin complexes during membrane constriction and fission suggesting a novel 'clusterase' model of the dynamin-mediated membrane fission.

    Visualization of the type III secretion mediated Salmonella–host cell interface using cryo-electron tomography

    Donghyun Park et al.
    Visualization of the type III secretion mediated Salmonella-host cell interface reveals the intact translocon and the profound remodeling of the host membrane at unprecedented resolution.
