(Submitter supplied) Regulation of RNA polymerase II (Pol II) elongation is a critical step in gene regulation. Here, we report that U1 snRNP recognition and transcription pausing at stable nucleosomes are linked through premature polyadenylation signal (PAS) termination. By generating RNA exosome conditional deletion mouse embryonic stem cells, we identified a large class of polyadenylated short transcripts in the sense direction destabilized by the RNA exosome. more...

(Submitter supplied) Transcription of the mammalian genome is pervasive, but productive transcription outside of protein-coding genes is limited by unknown mechanisms. In particular, although RNA polymerase II (RNAPII) initiates divergently from most active gene promoters, productive elongation occurs primarily in the sense-coding direction. Here we show in mouse embryonic stem cells that asymmetric sequence determinants flanking gene transcription start sites control promoter directionality by regulating promoter-proximal cleavage and polyadenylation. more...

(Submitter supplied) The expansion of introns within mammalian genomes poses a challenge for the production of full-length messenger RNAs (mRNA)s, with increasing evidence that these long AT-rich sequences present obstacles to transcription. Here, we investigate RNAPII elongation in mammalian cells at high resolution and demonstrate that RNAPII transcribes faster across introns. Moreover, we find that this acceleration is mediated by the association of U1 snRNP (U1) with the elongation complex at 5’ splice sites. more...

(Submitter supplied) Transcription by RNA polymerase II (Pol II) is coupled to pre-mRNA splicing, but the underlying mechanisms remain poorly understood. Co-transcriptional splicing requires assembly of a functional spliceosome on nascent pre-mRNA, but whether and how this influences Pol II transcription remains unclear. Here we show that inhibition of pre-mRNA branch site recognition by the spliceosome component U2 snRNP leads to a widespread and strong decrease in new RNA synthesis in human cells. more...
