(Submitter supplied) Elongation factor Paf1C regulates several stages of the RNA polymerase II (Pol II) transcription cycle, although it is unclear how it modulates Pol II distribution and progression in mammalian cells. We found that conditional ablation of Paf1 resulted in the accumulation of unphosphorylated and Ser5 phosphorylated Pol II around promoter proximal regions and within the first 20-30 kb of gene bodies, respectively. more...

(Submitter supplied) In vitro studies identified various factors including P-TEFb, SEC, SPT6, PAF1, DSIF, and NELF functioning at different stages of transcription elongation driven by RNA polymerase II (RNA Pol II). What remains unclear is how these factors cooperatively regulate pause/release and productive elongation in the context of living cells. Using an acute protein-depletion approach, we report that SPT6 depletion results in release of paused RNA Pol II. more...

(Submitter supplied) The control of promoter-proximal pausing and the release of RNA polymerase II (RNA Pol II) is a widely used mechanism for regulating gene expression in metazoans, especially for genes that respond to environmental and developmental cues. Here, we identify Pol II associated Factor 1 (PAF1) as a major regulator of promoter-proximal pausing. Knockdown of PAF1 leads to increased release of paused Pol II into gene bodies at thousands of genes. more...

(Submitter supplied) The Paf1 complex (Paf1C) is a conserved transcription elongation factor that regulates transcription elongation efficiency, facilitates co-transcriptional histone modifications, and impacts molecular processes linked to RNA synthesis, such as polyA site selection. Coupling of the activities of Paf1C to transcription elongation requires its association with RNA polymerase II (Pol II). Mutational studies in yeast identified Paf1C subunits Cdc73 and Rtf1 as important mediators of Paf1C association with Pol II on active genes. more...

(Submitter supplied) In this study, we reveal that BRD4 underlies a general 5'-elongation checkpoint that primes transcribing RNA polymerase II for 3'-RNA processing and transcription termination. BRD4-specific degradation impairs Pol II pause release, induces massive readthrough transcription, and RNA cleavage defects. Acute loss of BRD4 disrupts the recruitment of 3'-RNA processing factors.

(Submitter supplied) Release of promoter-proximal paused RNA polymerase II (Pol II) during early elongation is a critical step in transcriptional regulation in metazoan cells. Paused Pol II release is thought to require the kinase activity of cyclin-dependent kinase 9 (CDK9) for the phosphorylation of DRB sensitivity-inducing factor, negative elongation factor, and C-terminal domain (CTD) serine-2 of Pol II. We found that Pol II-associated factor 1 (PAF1) is a critical regulator of paused Pol II release, that positive transcription elongation factor b (P-TEFb) directly regulates the initial recruitment of PAF1 complex (PAF1C) to genes, and that the subsequent recruitment of CDK12 is dependent on PAF1C. more...

(Submitter supplied) The PAF1 complex (PAF1C) functions in multiple transcriptional and co-transcriptional processes. Although many aspects of the requirement for PAF1 in coding gene transcription have been heavily studied, the function of PAF1C at sites of non-coding transcription is poorly understood. eRNAs and PROMPTs are pervasive transcripts transcribed by RNA Polymerase II and rapidly degraded after 3’ endonucleolytic cleavage by the Integrator complex (Integrator). more...

(Submitter supplied) The RNA polymerase II (RNAPII) associated factor 1 complex (Paf1C) plays critical roles in modulating the release of paused RNAPII into productive elongation. However, regulation of Paf1C-mediated promoter-proximal pausing is complex and context dependent. In fact, in cancer cell lines opposing models of Paf1Cs’ role in RNAPII pause-release control have been proposed. Here we show that the Paf1C positively regulates RNAPII pause-release at both protein-coding genes and at enhancers in mouse embryonic stem cells (mESC). more...

(Submitter supplied) We have previously shown that the RNA polymerase II (Pol II)-DSIF complex associates with the PAF1 complex (PAF), RTF1 and SPT6 to form an activated elongation complex in vitro. Here we investigate the mechanisms that these factors use to stimulate Pol II elongation in vivo. We combine rapid factor depletion from human cells with genome-wide analyses of changes in RNA synthesis and occupancy with engaged Pol II. more...
