I performed fitting using Chimera for the TMD domain (previously modeled and individually deposited in the PDB), along with the following LBDs: LBD monomers from GluA4G2 Resting I (PDB ID: 9QDN) were fitted into chains A and D, while PDB entry 4U2R (GluA2 LBD, apo state) and PDB entry 4O3B (GluA2, aspartate-bound) were fitted into chains B and C, respectively. B-factors were reset, GluA4 residues were substituted, water molecules were removed, and NBQX was introduced. Subsequently, rigid-body refinement was performed using Phenix.
