::Description
Description Cytoplasmic polyadenylation is an evolutionarily conserved mechanism regulating translational activation of a set of quiescent maternal messenger RNAs (mRNAs) during early development. Cytoplasmic poly(A) elongation occurs in a wide range of species, ranging from clam to mouse. The relevance of this process during late oogenesis and early embryogenesis has been shown by studies in the mouse, Xenopus, and Drosophila. In mouse and Xenopus, the only vertebrates so far examined, the critical regulatory sequences, referred to as Cytoplasmic Polyadenylation Elements (CPEs), are AU-rich and located in the 3' untranslated region (3'-UTR) near the canonical nuclear polyadenylation element (AAUAAA), which also is required for proper poly(A) addition. The CPE has the general structure of UUUUUUAU. However, the CPE is not identical in all mRNAs and its position varies relative to AAUAAA (generally within 100 nucleotides). The minimal CPE capable to stimulate elongation of a poly(A) tail appears to be UUUUAU, and recent experiments show also the existence of substantial context and position effects on CPE function.
