Synaptic Activation Causes the mRNA for the IEG Arc to Localize Selectively near Activated Postsynaptic Sites on Dendrites

Abstract

Polyribosomal complexes beneath postsynaptic sites on dendrites provide a substrate for local translation of particular mRNAs, but the signals that target mRNAs to synapses remain to be defined. Here, we report that high frequency activation of the perforant path projections to the dentate gyrus causes newly synthesized mRNA for the immediate-early gene (IEG) Arc to localize selectively in activated dendritic segments. Newly synthesized Arc protein also accumulates in the portion of the dendrite that had been synaptically activated. The targeting of Arc mRNA was not disrupted by locally inhibiting protein synthesis, indicating that the signals for mRNA localization reside in the mRNA itself. This novel mechanism through which newly synthesized mRNA is precisely targeted to activated synapses is well suited to play a role in the enduring forms of activity-dependent synaptic modification that require protein synthesis.

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.
