Predicted to enable potassium channel regulator activity. Involved in several processes, including cellular response to L-glutamate; heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules; and nervous system development. Located in neuronal cell body and pericellular basket. Is integral component of membrane. Orthologous to human AMIGO1 (adhesion molecule with Ig like domain 1).
