Chemical shift assignments of calmodulin bound to the GluN1 C0 domain (residues 841–865) of the NMDA receptor

Neuroplasticity and synaptic transmission in the brain are regulated by N-methyl-D-aspartate receptors (NMDARs) that consist of hetero-tetrameric combinations of the glycine-binding GluN1 and glutamate-binding GluN2 subunits. Calmodulin (CaM) binds to the cytosolic C0 domain of GluN1 (residues 841–8...

Sumario:Neuroplasticity and synaptic transmission in the brain are regulated by N-methyl-D-aspartate receptors (NMDARs) that consist of hetero-tetrameric combinations of the glycine-binding GluN1 and glutamate-binding GluN2 subunits. Calmodulin (CaM) binds to the cytosolic C0 domain of GluN1 (residues 841–865) that may play a role in the Ca(2+)-dependent inactivation (CDI) of NMDAR channel activity. Dysregulation of NMDARs are linked to various neurological disorders, including Alzheimer’s disease, depression, stroke, epilepsy, and schizophrenia. Here, we report complete NMR chemical shift assignments of Ca(2+)-saturated CaM bound to the GluN1 C0 domain of the human NMDAR (BMRB no. 51715).
