Distinct genetic perturbations at the endogenous Atf4 locus uncouple polyadenylation loss from transcriptional readthrough
Transcription termination by RNA polymerase II (RNAPII) is coupled to co-transcriptional cleavage and polyadenylation directed by the canonical AAUAAA polyadenylation signal (PAS). However, the in vivo requirement of the canonical PAS for termination fidelity remains unclear. Here, we dissect PAS-dependent terminat...
