Summary: Predicted to enable SNAP receptor activity; SNARE binding activity; and arachidonic acid binding activity. Involved in exocytic insertion of neurotransmitter receptor to postsynaptic membrane and vesicle-mediated transport in synapse. Acts upstream of or within exocytosis; long-term synaptic potentiation; and vesicle fusion. Located in several cellular components, including Schaffer collateral - CA1 synapse; cytoplasmic vesicle; and photoreceptor cell terminal bouton. Part of SNARE complex. Is active in glutamatergic synapse and postsynapse. Is expressed in several structures, including alimentary system; central nervous system; eye; genitourinary system; and respiratory system. Human ortholog(s) of this gene implicated in congenital diarrhea. Orthologous to human STX3 (syntaxin 3). [provided by Alliance of Genome Resources, Apr 2022]

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.
