Summary
Enables calcium-dependent protein binding activity and syntaxin-1 binding activity. Involved in synaptic vesicle exocytosis. Located in dendrite; neuronal cell body; and synapse. Part of synaptobrevin 2-SNAP-25-syntaxin-1a-complexin II complex. Is active in postsynapse and presynapse. Orthologous to human CPLX2 (complexin 2).

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.
