Research Progresses on Structure and Functions of the Cytoplasmic Polyadenylation Element Binding Proteins

The cytoplasmic polyadenylation element binding proteins(CPEB) are mRNA-binding proteins,and play great roles in invertebrates and vertebrates.In this paper,the research progresses on structure and biological functions of CPEB were reviewed,and the research results of the CPEB in translation repression and activation of mRNA,oogenesis,cellular senescence,development,and synaptic plasticity in neuron were summarized.The molecular mechanisms of related biological incidents were discussed.In the end,the research prospects of CPEB were presented.
