As shown in Fig. 1, the Drosophila t-SNAREs, syntaxin and SNAP-25, are localized not only to the synaptic terminal, but also on the entire axonal membrane (18, 19). However, the v-SNARE synaptobrevin is found exclusively with synaptic vesicles within the synapse (20).
Where are V-SNAREs located?
SNARE proteins are embedded in both the vesicle and cell membrane, and force them into close proximity. When the two membranes make contact, a small channel called the fusion pore forms and expands to release the vesicle’s contents out of the cell. Synaptobrevin-2 is a SNARE protein found in the vesicle membrane.
What do V-SNAREs interact with?
Interaction between v-SNARE and t-SNARE leads to the formation of the trans-SNARE complex (or SNAREpin), in which the four SNARE motifs assemble as a twisted parallel four-helical bundle, which catalyzes the apposition and fusion of the vesicle with the target compartment [6], [7], [8].
