Résumé UniProt
Component of NMDA receptor complexes that function as heterotetrameric, ligand-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium. Channel activation requires binding of the neurotransmitter glutamate to the epsilon subunit, glycine binding to the zeta subunit, plus membrane depolarization to eliminate channel inhibition by Mg(2+) (PubMed:7685113, PubMed:28126851, PubMed:26919761, PubMed:26875626, PubMed:28105280). Sensitivity to glutamate and channel kinetics depend on the subunit composition (PubMed:26919761).
Résumé Entrez
The protein encoded by this gene is a critical subunit of N-methyl-D-aspartate receptors, members of the glutamate receptor channel superfamily which are heteromeric protein complexes with multiple subunits arranged to form a ligand-gated ion channel. These subunits play a key role in the plasticity of synapses, which is believed to underlie memory and learning. Cell-specific factors are thought to control expression of different isoforms, possibly contributing to the functional diversity of the subunits. Alternatively spliced transcript variants have been described.
Implication dans la maladie
Neurodevelopmental disorder with or without hyperkinetic movements and seizures, autosomal dominant: An autosomal dominant neurodevelopmental disorder characterized by severe mental retardation and developmental delay, absent speech, muscular hypotonia, dyskinesia, and hyperkinetic movements. Cortical blindness, cerebral atrophy, and seizures are present in some patients.
Neurodevelopmental disorder with or without hyperkinetic movements and seizures, autosomal recessive: An autosomal recessive neurodevelopmental disorder characterized by severe mental retardation and psychomotor developmental delay, involuntary and stereotypic movements, spasticity, and inability to walk without support. Intractable seizures manifest in some patients.
Similitudes de séquence
Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family. NR1/GRIN1 subfamily.
Modification post-traductionnelle
NMDA is probably regulated by C-terminal phosphorylation of an isoform of NR1 by PKC. Dephosphorylated on Ser-897 probably by protein phosphatase 2A (PPP2CB). Its phosphorylated state is influenced by the formation of the NMDAR-PPP2CB complex and the NMDAR channel activity.
