    Complexin inhibits spontaneous release and synchronizes Ca2+-triggered synaptic vesicle fusion by distinct mechanisms

    Ying Lai et al.
    Building on previous work (Diao et al., 2012), we show that the mechanism by which complexin suppresses spontaneous fusion is distinct from the mechanism by which it synchronizes Ca2+-triggered fusion.

    Munc18-1-regulated stage-wise SNARE assembly underlying synaptic exocytosis

    Lu Ma et al.
    The Munc18-1 protein promotes formation of the t-SNARE complex and the half-zippered SNARE complex, two rate-limiting steps of SNARE assembly, to enhance membrane fusion.

    Munc18-1 catalyzes neuronal SNARE assembly by templating SNARE association

    Junyi Jiao et al.
    Sec1/Munc18-family proteins chaperone SNARE assembly via a common templating mechanism.

    Autoinhibition of Munc18-1 modulates synaptobrevin binding and helps to enable Munc13-dependent regulation of membrane fusion

    Ewa Sitarska et al.
    Biophysical and functional data strongly support the notion that Munc18-1 acts as a template to assemble the neuronal SNARE complex, and that inhibition of this activity underlies diverse forms of regulation of neurotransmitter release.

    Mechanistic insights into neurotransmitter release and presynaptic plasticity from the crystal structure of Munc13-1 C1C2BMUN

    Junjie Xu et al.
    The crystal structure of a large C-terminal fragment of Munc13-1 provides a key framework to understand how Munc13-1 mediates neurotransmitter release and presynaptic plasticity.

    Functional synergy between the Munc13 C-terminal C1 and C2 domains

    Xiaoxia Liu et al.
    Munc13 C-terminal domains synergize to coordinate synaptic vesicle docking, priming and fusion.

    Acetylated tubulin is essential for touch sensation in mice

    Shane J Morley et al.
    Increased stiffness of sensory neurons in the absence of microtubule acetylation renders mice profoundly insensitive to touch and pain.

    Common intermediates and kinetics, but different energetics, in the assembly of SNARE proteins

    Sylvain Zorman et al.
    The energy landscape of SNARE folding and assembly is optimized for efficient stage-wise membrane fusion.

    Structural principles of SNARE complex recognition by the AAA+ protein NSF

    K Ian White et al.
    Electron-cryomicroscopy structures of the supercomplex of NSF, αSNAP, and neuronal SNAREs in the presence of ATP under non-hydrolyzing conditions at 3.9 Å resolution reveal interactions between the N-terminal residues of SNAP-25 and NSF.

    The cargo receptor SURF4 promotes the efficient cellular secretion of PCSK9

    Brian T Emmer et al.
    A CRISPR-based genomic screen identifies the ER cargo receptor SURF4 as a key determinant in the secretion of PCSK9, a protein that regulates human cholesterol levels and cardiovascular disease risk.
