Elongation rate of RNA polymerase II affects pausing patterns across the 3’ UTR
Ontology highlight
ABSTRACT: Yeast mRNAs are polyadenylated at multiple sites in their 3’ untranslated regions (3’UTRs), and poly(A) site usage is regulated by the rate of transcriptional elongation by RNA polymerase II (Pol II). Slow Pol II derivatives favor upstream poly(A) sites and fast Pol II derivatives favor downstream poly(A) sites. Transcriptional elongation and polyadenylation are linked at the nucleotide level, presumably reflecting Pol II dwell time at each residue that influences the level of polyadenylation. Here, we investigate the relationship between Pol II pause sites and poly(A) sites within 3’UTRs.
