Question: What is the effect of CPEB3 binding to the CPE domain?

Context: CPEB (Cytoplasmic Polyadenylation Element Binding) proteins are a family of four RNA-binding proteins that regulate the translation of maternal mRNAs controlling meiotic cell cycle progression
The family of cytoplasmic polyadenylation element binding proteins CPEB1, CPEB2, CPEB3, and CPEB4 binds to the 3'-untranslated region (3'-UTR) of mRNA, and plays significant roles in mRNA metabolism and translation regulation.
This cytoplasmic polyadenylation element (CPE) is the binding platform for CPE-binding protein (CPEB), which promotes polyadenylation-induced translation.
