Conformational rearrangement of the NMDA receptor amino-terminal domain during activation and allosteric modulation
N-Methyl-D-aspartate receptors (NMDARs) activation involves closure of the GluN1 and GluN2 subunit ligand binding domains, which is regulated allosterically by the amino-terminal domain (ATD). Here, smFRET, used to monitor conformational rearrangements of the NMDAR ATD, reveals that glutamate bindin...

| Sumario: | N-Methyl-D-aspartate receptors (NMDARs) activation involves closure of the GluN1 and GluN2 subunit ligand binding domains, which is regulated allosterically by the amino-terminal domain (ATD). Here, smFRET, used to monitor conformational rearrangements of the NMDAR ATD, reveals that glutamate binding to GluN2 subunits elicits two identical, sequential steps of ATD dimer separation that are regulated by protons. |
