Protein Structure

UniProt Annotation

Function

NMDA receptor subtype of glutamate-gated ion channels possesses high calcium permeability and voltage-dependent sensitivity to magnesium. Activation requires binding of agonist to both types of subunits.

Subcellular Localization

Cell membrane; Multi-pass membrane protein. Cell junction, synapse, postsynaptic cell membrane; Multi-pass membrane protein.

Disease Associations

Epilepsy, focal, with speech disorder and with or without mental retardation (FESD) [MIM:245570]: A highly variable neurologic disorder with features ranging from severe early-onset seizures associated with delayed psychomotor development, persistent speech difficulties, and mental retardation to a more benign entity characterized by childhood onset of mild or asymptomatic seizures associated with transient speech difficulties followed by remission of seizures in adolescence and normal psychomotor development. The disorder encompasses several clinical entities, including Landau-Kleffner syndrome, epileptic encephalopathy with continuous spike and wave during slow-wave sleep, autosomal dominant rolandic epilepsy, mental retardation and speech dyspraxia, and benign epilepsy with centrotemporal spikes. {ECO:0000269PubMed:20890276, ECO:0000269PubMed:23033978, ECO:0000269PubMed:23933818, ECO:0000269PubMed:23933819, ECO:0000269PubMed:23933820}. Note=The disease is caused by mutations affecting the gene represented in this entry.Note=A chromosomal aberration involving GRIN2A has been found in a family with epilepsy and neurodevelopmental defects. Translocation t(16;17)(p13.2;q11.2).Note=GRIN2A somatic mutations have been frequently found in cutaneous malignant melanoma, suggesting that the glutamate signaling pathway may play a role in the pathogenesis of melanoma. {ECO:0000269PubMed:21499247}.
