Figure 7. Schematic Summary of ECD Conformational Changes in NMDAR.
Shown are the conformational changes of the extracellular ATD and LBD layers associated with the transition from the apo state to the antagonist-bound state (right), the agonist-bound state (middle) and the agonist/Ro25-6981-bound (left). The bottom panel shows top-down views of various LBD conformations at different states. At present there is no structure for an apo-state and thus the schematic is grey.
