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 Mg2+ (PubMed:8768735, PubMed:26919761, PubMed:26875626, PubMed:28105280). Sensitivity to glutamate and channel kinetics depend on the subunit composition; channels containing GRIN1 and GRIN2A have higher sensitivity to glutamate and faster kinetics than channels formed by GRIN1 and GRIN2B (PubMed:26919761, PubMed:26875626). Contributes to the slow phase of excitatory postsynaptic current, long-term synaptic potentiation, and learning (By similarity).By similarity4 Publications

Epilepsy, focal, with speech disorder and with or without mental retardation (FESD)12 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA 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.

Forms heterotetrameric channels composed of two zeta subunits (GRIN1), and two epsilon subunits (GRIN2A, GRIN2B, GRIN2C or GRIN2D) (in vitro) (PubMed:8768735, PubMed:26919761, PubMed:26875626, PubMed:28105280). Can also form heterotetrameric channels that contain at least one zeta subunit (GRIN1), at least one epsilon subunit, plus GRIN3A or GRIN3B. In vivo, the subunit composition may depend on the expression levels of the different subunits.

Found in a complex with GRIN1, GRIN3A and PPP2CB (By similarity).

Found in a complex with GRIN1 and GRIN3B (By similarity).

Interacts with AIP1 (By similarity).

Interacts with HIP1 and NETO1.

Interacts with SNX27 (via PDZ domain); the interaction is required for recycling to the plasma membrane when endocytosed and prevent degradation in lysosomes (By similarity).

Interacts with PDZ domains of PATJ and DLG4.

Interacts with LRFN2 (By similarity).

Interacts with RPH3A and DLG4; this ternary complex regulates NMDA receptor composition at postsynaptic membranes (By similarity).

Interacts with SORCS2 (By similarity).

Interacts with ARC; preventing ARC oligomerization (By similarity).
