The proposed model of the local 
CaMKII synthesis through the CaMKII–CPEB1 molecular loop. Here, the CaMKII molecule can be in inactive, active or active and phosphorylated state, whereas CPEB1 can be in unphosphorylated or phosphorylated state. The CaMKII molecule in each of the three states has a finite turnover time. A new CaMKII molecule is produced by CPEB1-dependent polyadenylation of CaMKII mRNA, which is represented by translation stage (T).
