Extended Data Fig. 5. Comparison of GluK2 structures with 4-fold symmetrical LBD layer.

Extended Data Fig. 5

a-d, Structures of GluK2Glu-4fold (a, green), GluK2 in complex with (2 S,4 R)-4-methylglutamate (SYM) in the putative desensitized state (b, GluK2SYM, PDB ID: 5KUF, cyan), GluK2 in the putative apo state (c, GluK2apo, PDB ID: 8F0O, orange) and their superposition (d) viewed parallel to the membrane. The agonist molecules Glu and SYM are shown as space-filling models. e-h, LBD tetramers in GluK2Glu-4fold (e), GluK2SYM (f), GluK2apo (g) and their superposition (h) viewed extracellularly. i-l, Individual LBDs from GluK2Glu-4fold (i), GluK2SYM (j), GluK2apo (k) and their superposition (l).
