Domain Architecture (Details)
InterPro domains assigned to SynO:
The ability of synapses to modify their synaptic strength in response to activity is a fundamental property of the nervous system and may be an essential component of learning and memory. There are three classes of ionotropic glutamate receptor.amely NMDA (N-methyl-D-aspartate).MPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazole-4-propionicacid) and kainate receptors. They are believed to play critical roles in synaptic plasticity. At many synapses in the brain.ransient activation of NMDA receptors leads to a persistent modification in the strength of synaptic transmission mediated by AMPA receptors and kainate receptors can act as the induction trigger for long-term changes in synaptic transmission .
  IPR001320:Ionotropic glutamate receptor
InterPro domains unassigned to SynO:
N-Methyl-D-aspartate (NMDA) receptors are members of the glutamate receptorchannel superfamily.hich mediate most of the fast excitory synaptictransmissions in the central nervous system. The superfamily consists of 3subtypes: kainate receptors.lpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors and N-methyl-D-aspartate (NMDA) receptors. The NMDAreceptor is highly permeable to calcium ions and plays a key role in theplasticity of synapses.hich is believed to underlie memory and learning.s well as the development of the nervous system. Abnormal activation hasbeen suggested to lead to neuronal cell death observed in many acute andchronic disorders such as ischemia.troke.lzheimers disease.ndHuntingdons disease .NMDA receptors possess 4 transmembrane (TM) helical domains in the C-terminal half of the sequence and require both glycine and glutamate foractivation.esulting in influx of calcium ions into the cell . Thereceptors can also be activated by polyamine.hey can be blocked bymagnesium ions.nhibited by zinc ions.nd modulated by arachidonic acid.Other non-NMDA glutamate receptors (e.g..ainate) are structurally similarto NMDA receptors.ut are functionally distinct.ossibly as a result ofamino acid substitutions at important positions in the sequence.

Synapse Ontology
Postsynaptic compartment is represented by a patch of plasma membrane containing a packed array of neurotransmitter receptors and by an underlying dense matrix, the postsynaptic density (PSD).
