CaMKII activation persistently segregates postsynaptic proteins via liquid phase separation
Open accessPublished version of a preprint
Abstract
Transient information input to the brain leads to persistent changes in synaptic circuits, contributing to the formation of memory engrams. Pre- and postsynaptic structures undergo coordinated functional and structural changes during this process, but how such changes are achieved by their component molecules remains largely unknown. We found that activated CaMKII, a central player of synaptic plasticity, undergoes liquid-liquid phase separation with the NMDA-type glutamate receptor subunit GluN2B. Due to CaMKII autophosphorylation, the condensate stably persists even after Ca 2+ is removed. The selective binding of activated CaMKII with GluN2B cosegregates AMPA receptors and the synaptic adhesion molecule neuroligin into a phase-in-phase assembly. In this way, Ca 2+-induced liquid-liquid phase separation of CaMKII has the potential to act as an activity-dependent mechanism to crosslink postsynaptic proteins, which may serve as a platform for synaptic reorganization associated with synaptic plasticity.

“However, in the LLPS study, even after long incubation the CaMKII-GluN2B CTD dissipated after removal of Ca2+ unless the kinase was allowed to autophosphorylate, albeit slowly.”

“As long as Ca2+/CaM is present, binding and phase separation are maintained even with a phosphonull mutant of T286 (T286A) (78, 169, 323, 377) or with a kinase-dead mutant of CaMKII (169, 323, 378, 379), although the binding of CaMKII to GluN2B is modestly enhanced by T286 phosphorylation (378).”

“For CaMKII co-condensation with GluN2B, our findings in HEK cells confirm prior results with cell-free assays20,21 indicating that Ca2+/CaM stimulation is sufficient for the induction of condensation but that pT286 is required for its maintenance beyond the initial stimulus.”

“Furthermore, when AMPAR/TARPs (represented by the CTD of the auxiliary TARP subunit Stargazin) and PSD-95 are added to the system, activation of CaMKII in the presence of ATP partitions AMPAR/TARPs and NMDARs into two different phases (FIGURE 8).”

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.
