Regulatory Mechanisms of Alternative Polyadenylation in Plants: Roles of Poly(A) Protein Complexes in Transcriptome Plasticity.
This review synthesizes recent advances in understanding of how polyadenylation protein complexes-including Cleavage and Polyadenylation Specificity Factors (CPSF), Cleavage stimulation Factors (CstF), and Cleavage Factors (CF)-interact with cis-regulatory elements to determine poly(A) site choice.
