General annotation (Comments)

Function

NMDA receptor subtype of glutamate-gated ion channels with reduced single-channel conductance, low calcium permeability and low voltage-dependent sensitivity to magnesium. Mediated by glycine. May play a role in the development of dendritic spines. May play a role in PPP2CB-NMDAR mediated signaling mechanism By similarity.

Subunit structure

Forms heteromeric channel of a zeta subunit (GRIN1), a epsilon subunit (GRIN2A, GRIN2B, GRIN2C or GRIN2D) and a third subunit (GRIN3A or GRIN3B). Does not form functional homomeric channels. Found in a complex with GRIN1, GRIN2A or GRIN2B and PPP2CB. Probably interacts with PPP2CB. No complex with PPP2CB is detected when NMDARs are stimulated by NMDA By similarity. Ref.7

Subcellular location

Cell membrane; Multi-pass membrane protein By similarity. Cell junction › synapse › postsynaptic cell membrane By similarity. Cell junction › synapse › postsynaptic cell membrane › postsynaptic density By similarity. Note: Enriched in post-synaptic plasma membrane and post-synaptic densities. Requires the presence of GRIN1 to be targeted at the plasma membrane By similarity.

Developmental stage

Expressed in fetal brain.

Post-translational modification

N-glycosylated By similarity.

Sequence similarities

Belongs to the glutamate-gated ion channel (TC 1.A.10) family. [View classification]
