Vesicular soluble NSF attachment protein receptor (v-SNARE) mediating vesicle docking and fusion to a specific acceptor cellular compartment. Functions in endoplasmic reticulum to Golgi transport and in early/recycling endosome to TGN transport as part of a SNARE complex. Has a S-palmitoyl transferase activity (By similarity). May be found in 2 different SNARE complexes. Probably cycles through vesicles between Golgi and endosomes. Belongs to the synaptobrevin family.
