Summary: Enables SNAP receptor activity and syntaxin-1 binding activity. Involved in presynaptic dense core vesicle exocytosis and regulation of neuron projection development. Acts upstream of or within several processes, including associative learning; long-term synaptic potentiation; and neurotransmitter secretion. Located in several cellular components, including presynaptic membrane; synaptic vesicle; and trans-Golgi network. Part of synaptobrevin 2-SNAP-25-syntaxin-1a-complexin I complex. Is active in glutamatergic synapse. Is expressed in adrenal gland; jaw; nervous system; and sensory organ. Used to study attention deficit hyperactivity disorder; obesity; schizophrenia; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in Down syndrome and congenital myasthenic syndrome 18. Orthologous to human SNAP25 (synaptosome associated protein 25).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
