Predicted to enable integrin binding activity. Involved in modulation of chemical synaptic transmission. Acts upstream of or within several processes, including locomotory exploration behavior; modulation of chemical synaptic transmission; and nervous system development. Located in cell surface; membrane raft; and perineuronal net. Is active in Schaffer collateral - CA1 synapse and glutamatergic synapse. Is expressed in several structures, including aorta tunica media; brain; heart; urinary system; and ventral grey horn. Orthologous to human TNR (tenascin R).
