Crystallographic studies have shown that non-NMDA glutamate receptors exhibit fourfold symmetry in the transmembrane ___domain in the closed state; however, structural data regarding channel opening is lacking. Using chimeric receptors, Wilding et al.provide evidence that this fourfold symmetry is maintained in the open state.
