Function
Contactin (CNTN) is a neuronal cell surface glycoprotein which associates with sodium channel and enhances the density of these channels on the plasma membrane in mammalian expression systems[1].
- Contactin-2 is a synaptic membrane protein involved in pathology of Alzheimer Disease[2].
- Contactin-4 , contactin-5 and contactin-6 are involved in brain developmen[3].
Disease
Mutations in contactin-4, contactin-5 and contactin-6 confer risk of autism [4].
