Enables SNAP receptor activity and syntaxin binding activity. Involved in several processes, including Golgi vesicle transport; regulated exocytosis; and triglyceride transport. Located in several cellular components, including cytoplasmic vesicle; filopodium; and lysosomal membrane. Part of SNARE complex. Is active in hippocampal mossy fiber to CA3 synapse. Is integral component of synaptic vesicle membrane. Orthologous to human VAMP7 (vesicle associated membrane protein 7). [provided by Alliance of Genome Resources, Apr 2022]
