Predicted to enable cell adhesion molecule binding activity; protein heterodimerization activity; and protein homodimerization activity. Predicted to be involved in several processes, including heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules; homophilic cell adhesion via plasma membrane adhesion molecules; and regulation of homophilic cell adhesion. Predicted to be located in membrane. Predicted to be integral component of plasma membrane. Predicted to be active in neuron projection. Orthologous to human TENM3 (teneurin transmembrane protein 3).
