CPLX2 (complexin 2)

Gene

• Entrez ID: 10814
• Gene name: Complexin 2
• Gene symbol: CPLX2
• Synonyms (NCBI Gene): 921-L, CPX-2, CPX2, Hfb1
• Chromosome: 5
• Chromosome location: 5q35.2
• Summary: 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 di
