| Annotation description: | SNAP= soluble N-ethylmaleimide fusion protein attachment protein. Subcellular fractionation and Western Blot with an isoform-specific antibody against alpha-SNAP indicates that alpha-SNAP is present in membrane and soluble fractions of synaptosomes (Fig.3). Immunohistochemical analysis indicates the presence of alphaSNAP in cell bodies of neuron and glia and in synapse-rich areas in some brain regions (e.g. hippocampal mossy fiber terminals (Fig. 4). Pre-embedding electron microscopy of tissue sections and crude synaptic membranes indicates the presence of diffuse alpha-SNAP immunoreactivity in both pre- and postsynaptic regions (Fig.6), often close to synaptic vesicles (e.g. Fig.5A, in the NMJ). Isoform-specific anti-SNAP antibodies were raised to the sequences:(C)LRIKKTIQGDEEDLR (anti-α-SNAP, residues 281-295 of α-SNAP). Immunoblotting analysis demonstrates the specificity of the antibody (Fig.1) |
