Poly(A) tails, present on almost every eukaryotic mRNA, were discovered over 50 years ago. Early experiments led to the hypothesis that poly(A) tails and the cytoplasmic poly(A)-binding protein promote translation and prevent mRNA degradation, but the details remained unclear. More recent data suggest that the role of poly(A) tails is much more complex: poly(A)-binding protein can stimulate poly(A) tail removal (deadenylation), and the poly(A) tails of stable, highly-translated mRNAs at steady state are much shorter than expected. Moreover, the rate of translation elongation impacts deadenylation. Together, the interplay between poly(A) tails, poly(A)-binding protein, translation, and mRNA decay plays a major role in regulating gene expression. In this review, we summarize recent work that is revolutionizing the field and changing our perspective on the roles of poly(A) tails in the cytoplasm. Specifically, we discuss the roles of poly(A) tails in translation and mRNA stability, and how poly(A) tails are removed by exonucleases (deadenylases) including Ccr4-Not and Pan2-Pan3. We also cover major topics of current research, including how deadenylation rate is determined, the integration of deadenylation with other cellular processes, and the function of the cytoplasmic poly(A)-binding protein. Finally, we provide an outlook for the future of research in this area.
