glutamate ionotropic receptor NMDA type subunit 1

From NCBI Gene:

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. [provided by RefSeq, Jul 2008]

From 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).

  • Neurodevelopmental disorder with or without hyperkinetic movements and seizures, autosomal dominant
  • NEURODEVELOPMENTAL DISORDER WITH OR WITHOUT HYPERKINETIC MOVEMENTS AND SEIZURES, AUTOSOMAL RECESSIVE

From UniProt:

Neurodevelopmental disorder with or without hyperkinetic movements and seizures, autosomal dominant (NDHMSD): 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. [MIM:614254]

Neurodevelopmental disorder with or without hyperkinetic movements and seizures, autosomal recessive (NDHMSR): 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. [MIM:617820]
