Single-molecule studies of SNARE complex assembly reveal parallel and antiparallel configurations.
Vesicle fusion in eukaryotes is thought to involve the assembly of a highly conserved family of proteins termed soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) into a highly stable parallel four-helix bundle. We have used intermolecular single-molecule fluorescence resonance energy transfer to characterize preassembled neuronal SNARE complexes consisting of synta...
متن کاملSingle-molecule studies of synaptotagmin and complexin binding to the SNARE complex.
The assembly of multiprotein complexes at the membrane interface governs many signaling processes in cells. However, very few methods exist for obtaining biophysical information about protein complex formation at the membrane. We used single molecule fluorescence resonance energy transfer to study complexin and synaptotagmin interactions with the SNARE complex in deposited lipid bilayers. Using...
متن کاملSingle-molecule studies of the neuronal SNARE fusion machinery.
SNAREs are essential components of the machinery for Ca(2+)-triggered fusion of synaptic vesicles with the plasma membrane, resulting in neurotransmitter release into the synaptic cleft. Although much is known about their biophysical and structural properties and their interactions with accessory proteins such as the Ca(2+) sensor synaptotagmin, their precise role in membrane fusion remains an ...
