The allosteric site, which modulates receptor function when bound to a ligand, is not occupied. NMDARs require the binding of two molecules of glutamate or aspartate and two of glycine [1] [2] The N-methyl-D-aspartate receptor (also known as the NMDA receptor or NMDAR), is a glutamate receptor and predominantly Ca 2+ ion channel found in neurons.

Glutamate is the most prominent neurotransmitter in the body, and is the main excitatory neurotransmitter, being present in over 50% of nervous tissue. [2] [3] Glutamate was initially discovered to be a neurotransmitter in insect studies in the early 1960s.
Glutamate is a very major constituent of a wide variety of proteins; consequently it is one of the most abundant amino acids in the human body. [1] Glutamate is formally classified as a non-essential amino acid, because it can be synthesized (in sufficient quantities for health) from α-ketoglutaric acid, which is produced as part of the citric acid cycle by a series of reactions whose ...
N-methyl-D-aspartate receptors are a class of ionotropic glutamate receptors.The NMDA receptor channel has been shown to be involved in long-term potentiation, an activity-dependent increase in the efficiency of synaptic transmission thought to underlie certain kinds of memory and learning.
The glutamate interacts with the postsynaptic NMDA receptors, which aids the sensitization of the dorsal horn. [5] Presynaptic neuronal voltage-gated N-calcium channels are largely responsible for the release of this glutamate as well as the neuropeptide, substance P. [5]
Glutamate [NMDA] receptor subunit zeta-1 is a protein that in humans is encoded by the GRIN1 gene. [5] [6]The protein encoded by this gene is a critical subunit of N-methyl-D-aspartate receptors, members of the glutamate receptor channel superfamily which are heteromeric protein complexes with multiple subunits arranged to form a ligand-gated ion channel.
Glutamate [NMDA] receptor subunit epsilon-1 is a protein that in humans is encoded by the GRIN2A gene. [5] With 1464 amino acids, the canonical GluN2A subunit isoform is large. GluN2A-short isoforms specific to primates can be produced by alternative splicing and contain 1281 amino acids.
