Function

[NMDZ1_RAT] 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.^[1]

Publication Abstract from PubMed

Excitatory neurotransmission mediated by the N-methyl-D-aspartate subtype of ionotropic glutamate receptors is fundamental to the development and function of the mammalian central nervous system. NMDA receptors require both glycine and glutamate for activation with NR1 and NR2 forming glycine and glutamate sites, respectively. Mechanisms to describe agonist and antagonist binding, and activation and desensitization of NMDA receptors have been hampered by the lack of high-resolution structures. Here, we describe the cocrystal structures of the NR1 S1S2 ligand-binding core with the agonists glycine and D-serine (DS), the partial agonist D-cycloserine (DCS) and the antagonist 5,7-dichlorokynurenic acid (DCKA). The cleft of the S1S2 'clamshell' is open in the presence of the antagonist DCKA and closed in the glycine, DS and DCS complexes. In addition, the NR1 S1S2 structure reveals the fold and interactions of loop 1, a cysteine-rich region implicated in intersubunit allostery.
