Subunit-Specific NMDA Receptor Trafficking to Synapses
Open accessAbstract
To elucidate mechanisms controlling the number and subunit composition of synaptic NMDA-Rs in hippocampal slice neurons, the NR1, NR2A, and NR2B subunits were optically and electrophysiologically tagged. The NR2 subunit directs delivery of receptors to synapses with different rules controlling NR2A and NR2B. Synaptic incorporation of NR2B-containing receptors is not limited by synaptic transmission nor enhanced by increased subunit expression. NR2A-containing receptors whose expression normally increases with age replace synaptic NR2B-containing receptors. Replacement is enhanced by increased NR2A expression and requires synaptic activity. Surprisingly, spontaneously released transmitter acting on synaptic NMDA-Rs is sufficient for replacement and reduces NMDA-R responses. Thus, as with AMPA-Rs, synaptic trafficking of NMDA-Rs is tightly regulated and has subunit-specific rules with functionally important consequences.

“The second approach utilizes mutations in the CTD of GluN2B that cannot bind CaMKII as replacement for the wt (CaMKII L1298A/R1300Q) (120, 121, 230) or either competing with overexpressed full-length constructs (GluN2B R1300S/Q1303D) (231) or competing by expressing just the wt GluN2B CTD (839–1482) (232). The results are highly variable as reviewed in Ref. 233, ranging from complete block of LTP”

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.
