Deadenylation and its regulation in eukaryotic cells

Abstract

Messenger RNA deadenylation is a process that allows rapid regulation of gene expression in response to different cellular conditions. The change of the mRNA poly(A) tail length by the activation of deadenylation might regulate gene expression by affecting mRNA stability, mRNA transport, or translation initiation. Activation of deadenylation processes are highly regulated and associated with different cellular conditions such as cancer, development, mRNA surveillance, DNA damage response, and cell differentiation. In the last few years, new technologies for studying deadenylation have been developed. Here we overview concepts related to deadenylation and its regulation in eukaryotic cells. We also describe some of the most commonly used protocols to study deadenylation in eukaryotic cells.
