    Position of UNC-13 in the active zone regulates synaptic vesicle release probability and release kinetics

    Keming Zhou et al.
    The precise position of UNC-13 at the active zone near a synapse depends on the N-terminus of the protein, and the C2A domain in particular, and is essential for accelerating neurotransmitter release.

    A proline-rich motif on VGLUT1 reduces synaptic vesicle super-pool and spontaneous release frequency

    Xiao Min Zhang et al.
    In mammals, the vesicular glutamate transporter 1 acquired a proline-rich sequence that negatively regulates the spontaneous release of glutamate by reducing the exchange of synaptic vesicles along the axon.

    Heterodimerization of UNC-13/RIM regulates synaptic vesicle release probability but not priming in C. elegans

    Haowen Liu et al.
    RIM binding UNC-13L C2A domain releases UNC-13L from an autoinhibitory homodimeric complex to become fusion-competent, and regulates probability of synaptic vesicle release in the post-priming process.

    Circular oligomerization is an intrinsic property of synaptotagmin

    Jing Wang et al.
    Calcium-binding synaptotagmins are involved in ring oligomer formation, which allows synaptotagmins to synchronize neurotransmitter release to Ca2+ influx.

    Incomplete vesicular docking limits synaptic strength under high release probability conditions

    Gerardo Malagon et al.
    The probability of occupancy of individual synaptic release sites at rest sets an upper limit to synaptic output when increasing action potential related calcium entry.

    An essential role of acetylcholine-glutamate synergy at habenular synapses in nicotine dependence

    Silke Frahm et al.
    Local elimination of acetylcholine synthesis in habenular neurons demonstrates a key role for vesicular synergy and neurotransmitter co-release in nicotine dependence.

    Primate prefrontal neurons signal economic risk derived from the statistics of recent reward experience

    Fabian Grabenhorst et al.
    Neurons in prefrontal cortex track the variance of experienced rewards to guide economic decisions.

    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.

    Presynaptic morphology and vesicular composition determine vesicle dynamics in mouse central synapses

    Laurent Guillaud et al.
    In central synapses, the mobility and supply of synaptic vesicles are determined by two independent biological factors: the morphological and structural organization of nerve terminals and the molecular signature of vesicles.

    Drosophila Synaptotagmin 7 negatively regulates synaptic vesicle release and replenishment in a dosage-dependent manner

    Zhuo Guan et al.
    Drosophila synaptotagmin 7 functions to restrict SV availability and release, but does not act as the Ca2+ sensor mediating the asynchronous release and facilitation remaining in synaptotagmin 1 mutants.
