The presence and intracellular distribution of vesicle-associated membrane protein-1 (VAMP-1) and VAMP-2 were investigated in the PC12 neuroendocrine cell line using isotype-specific polyclonal antibodies. VAMP-2 was detected in the total membrane fraction, while VAMP-1 was undetectable. Subcellular fractionation demonstrates that a substantial amount of the VAMP-2 (24-36%) is associated with dense core, catecholamine-containing granules (DCGs). This was confirmed by immunofluorescence microscopy. The L chain of tetanus neurotoxin, known to inhibit granule mediated secretion in permeabilized PC12 cells, as well as botulinum neurotoxins F and G, effectively cleaved DCG-associated VAMP-2. These data demonstrate that VAMP-2 is present on the secretory granules of PC12 cells.
