Summaries for CPLX2 Gene

Entrez Gene Summary for CPLX2 Gene

  • Proteins encoded by the complexin/synaphin gene family are cytosolic proteins that function in synaptic vesicle exocytosis. These proteins bind syntaxin, part of the SNAP receptor. The protein product of this gene binds to the SNAP receptor complex and disrupts it, allowing transmitter release. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for CPLX2 Gene

CPLX2 (Complexin 2) is a Protein Coding gene. Diseases associated with CPLX2 include Huntington Disease and Schizophrenia. Among its related pathways are Synaptic vesicle cycle and Neuroscience. Gene Ontology (GO) annotations related to this gene include syntaxin binding and SNARE binding. An important paralog of this gene is CPLX1.

UniProtKB/Swiss-Prot for CPLX2 Gene

  • Negatively regulates the formation of synaptic vesicle clustering at active zone to the presynaptic membrane in postmitotic neurons. Positively regulates a late step in exocytosis of various cytoplasmic vesicles, such as synaptic vesicles and other secretory vesicles. Also involved in mast cell exocytosis (By similarity).
