Using this framework to analyze the SM (Sec1/Munc18)-SNARE ( N -ethylmaleimide-sensitive factor activating protein receptor) system in exocytic membrane fusion in yeast and neurons, we find that the SM-SNARE network motifs of yeast and neurons show distinct dynamical behaviors. (biomedcentral.com)
We identify the closed binding mode of neuronal SM (Munc18-1) and SNARE (syntaxin-1) as the key factor leading to mechanistic divergence of membrane fusion systems in yeast and neurons. (biomedcentral.com)
This inhibition reflects the binding of Munc18-1 to a closed conformation of the target-SNARE syntaxin1. (jneurosci.org)
The controversy would be solved if binding to closed syntaxin1 were shown to be stimulatory for vesicle fusion and/or additional essential interactions were identified between Munc18-1 and the fusion machinery. (jneurosci.org)
A mutation that diminished Munc18 binding to syntaxin1 in vitro attenuated the vesicle-docking step but rescued vesicle priming in excess of docking. (jneurosci.org)
Conversely, expressing the Munc18-2 isoform, which also displays binding to closed syntaxin1, rescued vesicle docking identical with Munc18-1 but impaired more downstream vesicle priming steps. (jneurosci.org)
In conclusion, binding of Munc18-1 to closed syntaxin1 stimulates vesicle docking and a distinct interaction mode regulates the consecutive priming step. (jneurosci.org)
This binding mode prompted the "negative regulator" hypothesis according to which Munc18-1 sequesters syntaxin1 and inhibits exocytosis. (jneurosci.org)
The results show that vesicle docking correlates with the ability of Munc18-1 to bind to closed syntaxin1. (jneurosci.org)
