3′-End Processing of Eukaryotic mRNA: Machinery, Regulation, and Impact on Gene Expression

Formation of the 3′ end of a eukaryotic mRNA is a key step in the production of a mature transcript. This process is mediated by a number of protein factors that cleave the pre-mRNA, add a poly(A) tail, and regulate transcription by protein dephosphorylation. Cleavage and polyadenylation specificity...
