    SNAP-25 is a neuronal SNARE protein required for synaptic vesicle exocytosis and neurite outgrowth. Here we show that in addition to synaptic staining, SNAP-25 immunoreactivity is also localized to an intracellular, perinuclear compartment of retinal neurons. Double-labeling with an antibody against the 58 kD resident protein of the trans-golgi network indicates that the intracellular SNAP-25 is localized to the Golgi complex. Immuno-electron microscopic localization of SNAP-25 confirmed its presence on the Golgi apparatus of photoreceptors, bipolar cells, amacrine cells and ganglion cells in the retina. These data implicate SNAP-25 in the trafficking of Golgi- derived vesicles in neurons in addition to the synaptic vesicle cycle.
