Research Abstract

Ca2+/Calmodulin-dependent protein kinase II (CaMKII) has been shown to play a major role in establishing memories through complex molecular interactions including phosphorylation of multiple synaptic targets. Here we reconstituted Ca2+/Calmodulin-dependent CaMKII autophosphorylation in the presence of protein phosphatase 1 in vitro, and found that CaMKII phosphorylation shows a switch-like response with history dependence (hysteresis) only in the presence of an N-methyl-D-aspartate (NMDA) receptor-derived peptide. This hysteresis may be crucial for induction and maintenance of long-term synaptic plasticity at synapses.
