SNX4 influences synaptic vesicle recruitment at the active zone, linking endosomal sorting to docked vesicle density and modulating neurotransmission efficiency during sustained activity.
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.

A model for synchronous neurotransmitter release suggests that when not in the presence of calcium ions, Synaptotagmin proteins form ring-like structures between the vesicle and plasma membrane that prevent spontaneous fusion.

The crucial regulator of brain function, mTOR, signals through distinct macromolecular complexes to control how synaptic vesicles are released from the presynaptic terminal.
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.

Biochemical fractionation of vesicle sub-populations and in vitro reconstitution studies reveal that Lupus La protein mediates the selective sorting of miR-122 into extracellular vesicles in vitro and in vivo.
Release site heterogeneity represents a previously unknown level of structural and functional organization within individual active zones in central synapses, which determines the spatiotemporal dynamics of multi-vesicular release.
Single synaptic vesicle imaging shows that kinetically distinct endocytic pathways are differentially regulated by calcium and temperature, and influence the fidelity of synaptic vesicle protein retrieval.
