VAMP-1, also known as vesicle-associated membrane protein, is an 18kDa member of the synaptobrevin family of proteins. It is expressed in neurons, neutrophils, and skeletal muscle cells, and participates in vesicle fusion with the plasma membrane (1). Synaptobrevins, Syntakins and the 25kDa synaptosomal associated SNAP25 are the main components of a protein complex involved in the docking and/or fusion of synaptic vesicles with the presynaptic membrane (2). VAMP-1 is also one of the key proteins in the SNARE complex which is involved in regulated exocytosis (3).
