Abstract

Recent studies show that AMPA receptor (-R) trafficking is important in synaptic plasticity. However, the signaling controlling this trafficking is poorly understood. Small GTPases have diverse neuronal functions and their perturbation is responsible for several mental disorders. Here, we examine the small GTPases Ras and Rap in the postsynaptic signaling underlying synaptic plasticity. We show that Ras relays the NMDA-R and CaMKII signaling that drives synaptic delivery of AMPA-Rs during long-term potentiation. In contrast, Rap mediates NMDA-R-dependent removal of synaptic AMPA-Rs that occurs during long-term depression. Ras and Rap exert their effects on AMPA-Rs that contain different subunit composition. Thus, Ras and Rap, whose activity can be controlled by postsynaptic enzymes, serve as independent regulators for potentiating and depressing central synapses.

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.
