Summary: Enables SNARE binding activity and neurotransmitter transmembrane transporter activity. Involved in insulin secretion; regulation of synaptic vesicle fusion to presynaptic active zone membrane; and synaptic vesicle exocytosis. Acts upstream of or within regulation of neurotransmitter secretion. Located in cytosol; plasma membrane; and synapse. Is active in photoreceptor ribbon synapse; presynaptic active zone membrane; and synaptic vesicle membrane. Is expressed in brain; cerebral cortex; and cortical layer V. Orthologous to human CPLX3 (complexin 3). [provided by Alliance of Genome Resources, Dec 2024]

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.
