摘要
Munc13 proteins are essential in neurotransmitter release, controlling the priming of synaptic vesicles to a release-ready state. The sequences responsible for this priming activity are unknown. Here we identify a large alpha-helical domain of mammalian Munc13-1 that is autonomously folded and is sufficient to rescue the total arrest in neurotransmitter release observed in hippocampal neurons lacking Munc13s.
