Annotation description:Littleton et al used a Drosophila temperature-sensitive paralytic mutation in NSF (termed "comatose") that slowly blocks synaptic transmission while syntaxin and SNARE complexes accumulate on synaptic vesicles. Figure 4 shows that increased temperature leads to accumulation of 70S SNARE assembled SNARE complex. These findings suggest that NSF mediates disassembly of the SNARE complex after fusion, and that disassembly is required for the re-generation of the SNARE-fusion machinery.

Additional literature:In this paper, Söllner et al. isolated bovine brain membrane and incubate it with purified NSF and
a-SNAP. They found that in the presence of ATP, NSF and a-SNAP the SNARE-complex consisting of synaptobrevin (VAMP-2), syntaxin 1, and SNAP-25 is disassembled in an ATP-dependent manner. @ PMID:8221884
