FIGURE 4: A diagram displaying the interaction of Munc18-1 an SNARE proteins along the stages of exocytosis.(A) The interaction between Munc18-1 and SNARE proteins, indicating that Munc18-1 favours the formation of the ternary SNARE complex where synaptobrevin binds preferably with the binary complex between syntaxin and SNAP25. (B) The stages from docking/priming, hemifusion state, leading to fusion pore formation and full fusion, with the action of respective Munc18-1 mutants and dnSNARE peptides. From Ref [26]
