Article Title: | The specificity of SNARE-dependent fusion is encoded in the SNARE motif |
Abstract: | Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins constitute the core of the fusion machinery, and isolated SNAREs fuse membranes with exquisite specificity by cognate pairing. Most SNAREs have a membrane-spanning region, an N-terminal domain, and a membrane proximal SNARE motif domain. Although the SNARE motif is critical for SNARE complex formation, is it the sole determinant of the specificity of SNARE-dependent fusion? To test this, we make use of a SNARE complex functioning in the late endosomal compartment in yeast. Studying this complex and the previously identified early endosomal SNARE complex, we find that the specificity of fusion resides in the SNARE motifs. |
