A	PF05008	Vesicle transport v-SNARE protein N-terminus (V-SNARE)	Vesicle transport v-SNARE protein N-terminus	V-SNARE proteins are required for protein traffic between eukaryotic organelles. The v-SNAREs on transport vesicles interact with t-SNAREs on target membranes in order to facilitate this [1]. This domain is the N-terminal half of the V-Snare proteins ...
