Synaptic vesicle fusion involves a multi-protein assembly called the SNARE complex that is tightly regulated both spatially and temporally. Here Kavanagh et al. show that after vesicle fusion and SNARE complex disassembly in the synapse, the SNARE protein syntaxin1a is sequestered in a monomeric form by munc18-1, preventing ectopic SNARE complex assembly.
