General annotation (Comments)

Function

NMDA receptor subtype of glutamate-gated ion channels possesses high calcium permeability and voltage-dependent sensitivity to magnesium. Mediated by glycine. Plays a key role in synaptic plasticity, synaptogenesis, excitotoxicity, memory acquisition and learning. It mediates neuronal functions in glutamate neurotransmission. Is involved in the cell surface targeting of NMDA receptors. Ref.18

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); disulfide-linked By similarity. Found in a complex with GRIN2A or GRIN2B, GRIN3A and PPP2CB. Found in a complex with GRIN2A or GRIN2B and GRIN3B By similarity. Interacts with DLG4 and MPDZ. Interacts with LRFN1 and LRFN2. Interacts with GCOM1. Ref.11 Ref.13 Ref.14 Ref.15 Ref.17

Subcellular location

Cell membrane; Multi-pass membrane protein By similarity. Cell junctionsynapsepostsynaptic cell membrane By similarity. Cell junctionsynapsepostsynaptic cell membranepostsynaptic density By similarity. Note: Enriched in post-synaptic plasma membrane and post-synaptic densities By similarity.

Post-translational modification

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. Ref.7 Ref.12

Sequence similarities

Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family. NR1/GRIN1 subfamily. [View classification]
