Alternative cleavage and polyadenylation: key regulatory mechanisms in health and disease
4 Jul 2025
Abstract excerpt
Alternative polyadenylation (APA) is a critical post-transcriptional regulatory mechanism that generates diverse mRNA isoforms by selecting different polyadenylation sites within pre-mRNAs, thereby modulating the length of the 3' untranslated region (3' UTR), thereby fine-tuning gene expression and protein synthesis. APA regulation involves conserved cis-acting elements, trans-acting factors, and key protein...
