Summary: Predicted to enable calcium-dependent protein binding activity and syntaxin-1 binding activity. Involved in positive regulation of synaptic plasticity and regulation of synaptic vesicle fusion to presynaptic active zone membrane. Located in glutamatergic synapse. Is active in calyx of Held.

Complexin Suppresses Spontaneous Exocytosis by Capturing the Membrane-Proximal Regions of VAMP2 and SNAP25.
Title: Complexin Suppresses Spontaneous Exocytosis by Capturing the Membrane-Proximal Regions of VAMP2 and SNAP25.
data suggest that CPLX2 inhibits spontaneous secretion of IgM and IgG1 from splenic antibody-secreting cells (ASCs). This study provides new insight into the mechanism of antibody secretion of ASCs.

the C2B domain of syt1, independent of complexin, is the molecular clamp that arrests synaptic vesicles prior to Ca(2+)-triggered fusion.
Title: Synaptotagmin 1 clamps synaptic vesicle fusion in mammalian neurons independent of complexin.
We describe a high degree of structural similarity between the CpxII CTD and the SNAP25-SN1 domain (C-terminal half) and show that the CTD peptide lowers the rate of SDS-resistant SNARE complex formation in vitro. Moreover, corresponding CpxII:SNAP25 chimeras do restore complexin's function and even 'superclamp' tonic secretion.

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.
