N-methyl-D-aspartate receptors: different subunit requirements for binding of glutamate antagonists, glycine antagonists, and channel-blocking agents

Abstract

Expression of the NR-1 subunit in Xenopus oocytes produces channels that respond to glutamate and are blocked by competitive and noncompetitive antagonists of the N-methyl-D-aspartate (NMDA) receptor. Ionic conductances through these channels are increased by coexpression with NR-2 receptor subunits. We have characterized the pharmacological properties of NMDA receptors assembled from combinations of subunits expressed in transfected cells, to determine the minimum subunit requirements for binding of competitive glutamate antagonists, glycine antagonists, and channel-blocking agents, as detected by ligand-binding experiments. Expression of NR-1a alone produced glycine antagonist binding, whereas the combination of NR-1a and NR-2A was needed to produce binding sites for glutamate antagonists and channel-blocking agents. These results suggest that functional NMDA receptors assemble from these subunits. However, differences in the pharmacological effects of NMDA and polyamines show that not all characteristics of native NMDA receptors are reproduced by this combination of subunits.

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.
