Background Information

CPEB3, the cytoplasmic polyadenylation element-binding protein 3, contains a Q/N-rich domain at its N-termina which is required for the aggregation of CPEB3. The expression of CPEB3 is downregulated in cervical cancer and hepatocellular carcinoma compared with normal tissue. It has been reported that the aggregation and activity of CPEB3 is controlled by SUMOylation. CPEB3 is SUMOylated in hippocampal neurons in the basal state while converted into an active form which is associated with a decrease of SUMOylation and an increase of aggregation. CPEB3 is expressed in cytoplasma in unstimulated neurons but translocates to the nucleus following neuronal stimulation.
