    Identification of a Munc13-sensitive step in chromaffin cell large dense-core vesicle exocytosis

    Kwun Nok M Man et al.
    Munc13 proteins are key determinants of large dense-core vesicle (LDCV)-dependent catecholamine release in chromaffin cells.

    Elevated synaptic vesicle release probability in synaptophysin/gyrin family quadruple knockouts

    Mathan K Raja et al.
    Synaptophysins and gyrins dampen synaptic strength selectively at low frequencies, hinting that synaptic transmission may play a frequency filtering role in biological computation that is more general than currently envisioned.

    Myosin V functions as a vesicle tether at the plasma membrane to control neurotransmitter release in central synapses

    Dario Maschi et al.
    Synaptic vesicles undergo reversible tethering at the plasma membrane which is activity- and myosin V- dependent.

    Analysis of protein phosphorylation in nerve terminal reveals extensive changes in active zone proteins upon exocytosis

    Mahdokht Kohansal-Nodehi et al.
    Global phosphoproteomic analysis in nerve terminal during exocytosis reveals 252 uniquely regulated phosphosites, highlighting complex regulation of active zone proteins at multiple sites and the role of specific kinases/phosphatases.

    Synaptotagmin 7 is targeted to the axonal plasma membrane through γ-secretase processing to promote synaptic vesicle docking in mouse hippocampal neurons

    Jason D Vevea et al.
    Synaptotagmin 7 is asymmetrically localized to the axonal plasma membrane through γ-secretase processing to promote vesicle docking during short-term synaptic plasticity in mouse hippocampal neurons.

    Otoferlin acts as a Ca2+ sensor for vesicle fusion and vesicle pool replenishment at auditory hair cell ribbon synapses

    Nicolas Michalski et al.
    Targeted mutations in a Ca2+-binding site of otoferlin, a transmembrane protein of synaptic vesicles defective in a recessive form of deafness, reveal its Ca2+ sensor role both for vesicle fusion and vesicle pool replenishment.

    Distinct modes of endocytotic presynaptic membrane and protein uptake at the calyx of Held terminal of rats and mice

    Yuji Okamoto et al.
    Capacitance measurements and pH imaging reveal distinct modes of uptake for endocytotic presynaptic membrane and proteins.

    An autoinhibitory clamp of actin assembly constrains and directs synaptic endocytosis

    Steven J Del Signore et al.
    Autoinhibition allows synaptic endocytic actin regulators to pre-deploy to synaptic membranes at high concentrations and constrains actin assembly to productive events.

    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.

    Evoked transients of pH-sensitive fluorescent false neurotransmitter reveal dopamine hot spots in the globus pallidus

    Jozsef Meszaros et al.
    Dopamine release within the mouse external globus pallidus, an area of very sparse innervation, is observed and described for the first time through a new technique: flashing false fluorescent neurotransmitters.
