Summary
This gene encodes a member of the glutamate-gated ion channel protein family. The encoded protein is an N-methyl-D-aspartate (NMDA) receptor subunit. NMDA receptors are both ligand-gated and voltage-dependent, and are involved in long-term potentiation, an activity-dependent increase in the efficiency of synaptic transmission thought to underlie certain kinds of memory and learning. These receptors are permeable to calcium ions, and activation results in a calcium influx into post-synaptic cells, which results in the activation of several signaling cascades. Disruption of this gene is associated with focal epilepsy and speech disorder with or without cognitive disability. Alternative splicing results in multiple transcript variants.

    Signalling to ERKs, organism-specific biosystemNeurotrophins utilize multiple pathways to activate ERKs (ERK1 and ERK2), a subgroup of the large MAP kinase (MAPK) family, from the plasma membrane. The major signalling pathways to ERKs are via RAS...
  • Signalling to RAS, organism-specific biosystem (from REACTOME)
    Signalling to RAS, organism-specific biosystemSignalling through Shc adaptor proteins appears to be identical for both NGF and EGF. It leads to a fast, but transient, MAPK/ERK activation, which is insufficient to explain the prolonged activation...
  • Signalling to p38 via RIT and RIN, organism-specific biosystem (from REACTOME)
    Signalling to p38 via RIT and RIN, organism-specific biosystemRIT and RIN are two small guanine nucleotide binding proteins that share more than 50% sequence identity with RAS, including highly conserved core effector domains. Unlike RAS, the C termini of RIT a...

    Transmission across Chemical Synapses, organism-specific biosystemChemical synapses are specialized junctions that are used for communication between neurons, neurons and muscle or gland cells. The synapse involves a pre-synaptic neuron and a post-synaptic neuron,...
  • Unblocking of NMDA receptor, glutamate binding and activation, organism-specific biosystem (from REACTOME)
    Unblocking of NMDA receptor, glutamate binding and activation, organism-specific biosystemAt resting membrane potential the NMDA receptor is blocked by extracellular Mg2+ ions and therefore is not activated in this state by ligands (glutamate, glycine, NMDA). The voltage block is removed ...
  • VEGFA-VEGFR2 Pathway, organism-specific biosystem (from REACTOME)
    VEGFA-VEGFR2 Pathway, organism-specific biosystemAngiogenesis is the formation of new blood vessels from preexisting vasculature. One of the most important proangiogenic factors is vascular endothelial growth factor (VEGF). VEGF exerts its biologic...
  • VEGFR2 mediated cell proliferation, organism-specific biosystem (from REACTOME)
    VEGFR2 mediated cell proliferation, organism-specific biosystemVEGFR2 stimulates ERK not via GRB2-SOS-RAS, but via pY1175-dependent phosphorylation of PLC gamma and subsequent activation of PKCs. PKC plays an important mediatory role in the proliferative Ras/Raf...
  • cAMP signaling pathway, organism-specific biosystem (from KEGG)

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
