Predicted to enable mRNA 3'-UTR binding activity; ribosome binding activity; and translation regulator activity, nucleic acid binding. Involved in several processes, including cellular response to glucose starvation; ionotropic glutamate receptor signaling pathway; and negative regulation of neuron apoptotic process. Located in cytoplasm; dendrite; and nucleus. Is active in postsynapse. Orthologous to human CPEB4 (cytoplasmic polyadenylation element binding protein 4).
