Abstract: N-methyl-D-aspartate receptors (NMDARs) consist of glycine-binding GluN1 and glutamate-binding GluN2 subunits that form tetrameric ion channels. NMDARs in the brain are important for controlling neuronal excitability to promote synaptic plasticity. The cytoskeletal protein, α-actinin-1 (100 kDa, called ACTN1) binds to the cytosolic C0 domain of GluN1 (residues 841–865) that may play a role in the Ca 2+ -dependent desensitization of NMDAR channels. Mutations that disrupt NMDAR channel function are linked to Alzheimer’s disease, depression, stroke, epilepsy, and schizophrenia. NMR chemical shift assignments are reported here for the C-terminal EF-hand domain of ACTN1 (residues 824–892, called ACTN_EF34) and ACTN_EF34 bound to the GluN1 C0 domain (BMRB numbers 52385 and 52386, respectively).
