Transcriptional control shapes a cell's transcriptome composition, but it is RNA processing that refines its expression. The untranslated regions (UTRs) of mRNA are hotspots for regulatory control. Features in these can impact mRNA stability, localisation and translation. Here we describe how alternative cleavage and polyadenylation can change mRNA fate by changing the length of its 3'UTR.
- 3'-End formation
- Alternative polyadenylation
