    Summary
    Enables SNAP receptor activity and SNARE binding activity. Involved in chemical synaptic transmission; regulation of short-term neuronal synaptic plasticity; and synaptic vesicle transport. Located in terminal bouton. Part of SNARE complex. Is expressed in adult head; central nervous system; chordotonal organ; and neurons. Human ortholog(s) of this gene implicated in Down syndrome and congenital myasthenic syndrome 18. Orthologous to several human genes including SNAP25 (synaptosome associated protein 25).

    What's a GeneRIF?
    1. these results indicate that SNAP-25-R206 and syntaxin-D253 play a major role in neuroexocytosis and support a radial assembly of several SNARE complexes interacting via the ionic couple formed by these two residues.
