Snippet: The juxtamembrane motif of VAMP2 also contains a hydrophobic stretch (residues 88-93) buried in the nonpolar phase of the membrane bilayer . We observed that SNARE-Munc18-1-mediated liposome fusion was strongly inhibited when this hydrophobic stretch was deleted or mutated into alanines ( Figure 4B ). Thus, like the basic residues, the hydrophobic stretch is critical for the function of the juxtamembrane motif in membrane fusion......
