(Submitter supplied) Hypoxia-inducible factor-1 (HIF-1) is a transcription factor that acts as a master regulator of O2 homeostasis in metazoan species by binding to hypoxia response elements (HREs) and activating the transcription of hundreds of genes in response to reduced O2 availability. RNA polymerase II (Pol II) initiates transcription of many HIF target genes under non-hypoxic conditions, but pauses after 20-100 nucleotides and requires HIF-1 binding for release. more...

(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 release of paused RNA polymerase II (RNAPII) from promoter-proximal regions is tightly controlled to ensure proper regulation of gene expression. The elongation factor PTEF-b is known to release paused RNAPII via phosphorylation of the RNAPII C-terminal domain by its cyclin-dependent kinase component, CDK9. However, the signal and stress-specific roles of the various RNAPII-associated macromolecular complexes containing PTEF-b/CDK9 are not yet clear. more...

(Submitter supplied) More than 30% of genes in higher eukaryotes are regulated by RNA Polymerase II (Pol II) promoter proximal pausing. Pausing is released by the positive transcription elongation factor complex (P-TEFb). However, the exact mechanism by which this occurs and whether phosphorylation of the carboxyl-terminal domain of Pol II is involved in the process remains unknown. We previously reported that JMJD5 could generate tailless nucleosomes at position +1 from transcription start sites (TSS) thus perhaps enable progression of Pol II. more...

(Submitter supplied) We have previously shown that RNA polymerase II (Pol II) pause release and transcriptional elongation involve phosphorylation of the factor TRIM28 by the DNA damage response (DDR) kinases ATM and DNA-PK. Here, we report a significant role for DNA breaks and DDR signaling in the mechanisms of transcriptional elongation in stimulus-inducible genes in humans. Our data show the enrichment of TRIM28 and γH2AX on serum-induced genes and the important function of DNA-PK for Pol II pause release and transcriptional activation-coupled DDR signaling on these genes. more...

(Submitter supplied) To investigate how HIF-1 recruits FACT and RNF20/40 to mediate histone ubiquitination and facilitate transcription of target genes, we established stable cell lines in which HIF-1, FACT or RNF20/40 has been knocked down by shRNA. We performed gene expression profiling analysis using data obtained from RNA-seq of 4 different cells at 20% and 1% oxygen condition.

(Submitter supplied) Efficient release of promoter-proximally paused Pol II into productive elongation is essential for gene expression. Recently, we reported that the Integrator complex can bind paused Pol II and drive premature transcription termination, potently attenuating the activity of target genes. Premature termination requires RNA cleavage by the endonuclease subunit of Integrator, but the roles of other Integrator subunits in gene regulation have yet to be elucidated. more...

(Submitter supplied) The transition of RNA polymerase II (Pol II) from initiation to productive elongation is a central, regulated step in metazoan gene expression. At many genes, Pol II pauses stably in early elongation, remaining engaged with the 25-60 nucleotide-long nascent RNA for many minutes while awaiting signals for release into the gene body. However, a number of genes display highly unstable promoter Pol II, suggesting that paused polymerase terminates transcription at these promoters and releases a short, non-functional RNA. more...

(Submitter supplied) The Pol II transcription cycle is ordered by CDKs and phosphatases. In fission yeast, Cdk9 phosphorylates carboxy-terminal repeats (CTRs) of Spt5 while inhibiting PP1 during elongation. Transcription past the cleavage and polyadenylation signal (CPS) coincides with PP1-dependent Spt5 dephosphorylation and leads to Pol II pausing with phosphorylated CTD-Ser2 (pSer2). Here we show this switch is conserved in humans: Cdk9 inhibition decreases phosphorylation of both PP1g and Spt5-Thr806 (pThr806), and induces pSer2 upstream of the CPS, whereas PP1 depletion increases pThr806. 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...
