Abstract
Transcription and mRNA maturation are interdependent events. Although stimulatory connections between these processes within the same round of transcription are well described, functional coupling between separate transcription cycles remains elusive. Comparing time-resolved transcription profiles of single-copy integrated beta-globin gene variants, we demonstrate that a polyadenylation site mutation decreases transcription initiation of the same gene. Upon depletion of the 3' end processing and transcription termination factor PCF11, endogenous genes exhibit a similar phenotype. Readthrough RNA polymerase II (RNAPII) engaged on polyadenylation site-mutated tran...
