General description
Anti-SNAP-25 is developed in rabbit using a synthetic peptide corresponding to the N-terminus of human SNAP-25 conjugated to KLH as immunogen. This sequence is identical in SNAP-25 alternatively spliced forms SNAP-25A and SNAP-25B, in mouse, rat and chicken SNAP-25 and highly conserved (80-85%) in goldfish and zebrafish SNAP25. Whole antiserum is fractionated and then further purified by ion-exchange chromatography to provide the IgG fraction of antiserum that is essentially free of other rabbit serum proteins. Anti-SNAP-25 recognizes mouse SNAP-25 (25 kD). The antibody cross-reacts with rat SNAP-25. Applications include the detection and localization of SNAP-25 (25 kDa) by immunoblotting and immunohistochemistry. Staining of SNAP-25 in immunoblotting is specifically inhibited with SNAP-25 immunizing peptide (SNAP-25, mouse)

Biochem/physiol Actions
The molecular events leading to neurotransmitter release in the synaptic cleft are complex, involving multiple interacting proteins, generically termed SNAP receptors (SNAREs). It has been suggested that SNAP-25 and syntaxin on the neuronal plasma membrane (t-SNARE) and synaptobrevin/VAMP on the synaptic vesicle (v-SNARE) form a stable ternary complex. This core complex serves as a docking complex for two additional membrane fusion proteins, β-SNAP and NSF. ATP hydrolysis by NSF causes dissociation of the complex during priming of the exocytosis machinery. SNAP-25 induced reassembly and interaction with synaptotagmin (Syt), is thought to drive the Ca2+ -triggered vesicle-plasma membrane fusion and exocytosis. SNAP-25 has a key role in both developing and mature neurons. During development, SNAP-25 expression correlates with synaptogenesis, axonal growth and neuronal maturation and is found mainly in cell bodies of neonatal brain. In the adult nervous system, SNAP-25 is localized to presynaptic nerve terminals where it is conveyed by fast axonal transport.
SNAP-25 consists of two alternatively spliced isoforms SNAP-25a and SNAP-25b, differentially expressed in neurons and neuroendocrine cells. SNAP-25a and SNAP-25b differ by nine amino acids in the central domain. Two of these residues alter the relative positioning of clustered cysteine residues that are required for post-translational palmitoylation implicated in membrane anchoring, suggesting that the two SNAP-25 isoforms may play distinct roles in vesicular fusion events.
