Specific transcriptional pausing activates polyadenylation in a coupled in vitro system.

Abstract:

We have developed a coupled in vitro transcription-polyadenylation system to investigate RNA polymerase II (Pol II) termination, which depends on active polyadenylation of the nascent RNA. Specific G-rich sequences originally identified as binding sites for the transcription factor MAZ both pause Pol II and activate polyadenylation of an upstream poly(A) signal. They do not affect polyadenylation efficiency in an uncoupled cleavage assay. In contrast, pausing of Pol II elongation induced by a...
