Molecular basis of NMDA receptor functional diversity
Abstract
NMDA receptors (NMDARs) form glutamate-gated ion channels widely expressed in the central nervous system and highly permeable to calcium ions. NMDARs have always attracted much attention because of their central implications in numerous physiological and pathological processes including synaptic plasticity and excitotoxicity. Ever since the discovery of NMDARs three decades ago, it has been acknowledged that native NMDARs do not form a homogeneous population of receptors but rather exist as multiple subpopulations that differ in their functional properties and, presumably, physiopathological roles. NMDARs are in fact large multi-subunit complexes arranged into heteromeric assemblies composed of four homologous subunits within a repertoire of over 10 different subunits: eight GluN1 isoforms, four GluN2 subunits (A-D) and two GluN3 subunits (A and B). This review gives an overview of our current knowledge of the molecular basis underlying NMDAR functional heterogeneity. The modular architecture and expression profile of NMDAR subunits together with the basic principles of NMDAR operation are first introduced. The influence of subunit composition on receptor functional properties is then described, with emphasis put on the impact of differential incorporation of GluN1 and GluN2 subunits (the roles of GluN3 subunits being less well understood). The final part presents recent studies revealing the central, and largely unsuspected, role of the extracellular N-terminal region in generating functional diversity of NMDARs. Indeed, the identity of this region, which is distal to the membrane and precedes the agonist-binding domains, determines key biophysical and pharmacological attributes of the various NMDAR subtypes.

“…to the extracellular domains, the Cterminal tails of NMDAR subunits are unlikely to form a well-defined structure but rather contain a series of short motifs that interact with intracellular factors involved in receptor trafficking, anchoring and signaling (Lau & Zukin, 2007; Ryan et al., 2008).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
