Contactins are a subgroup of molecules belonging to the immunoglobulin superfamily that are expressed exclusively in the nervous system. These proteins are attached to the neuronal membrane by a GPI-anchor. The subgroup consists of six members now referred to as contactin 1-6,[1] but historically they had different names as shown in the table below:
