(Submitter supplied) Spt5 is a highly conserved RNA polymerase II (Pol II)-associated pausing and elongation factor. However, its impact on global elongation and Pol II processivity in mammalian cells has not been clarified. Here, we show that depleting Spt5 in mouse embryonic fibroblasts (MEFs) does not cause global elongation defects or decreased elongation rates. Instead, in the absence of Spt5, a fraction of Pol II molecules are dislodged during elongation thus decreasing the number of Pol II complexes that complete the transcription cycle. more...

(Submitter supplied) Transcription machinery progression is governed by multitasking regulators including SPT5, an evolutionarily conserved factor implicated in virtually all transcriptional steps from enhancer activation to termination. Yet its mechanistic understanding in human cells remains incomplete. Here we utilize rapid degradation system and reveal crucial function of SPT5 in maintaining cellular and chromatin Pol II levels. more...

(Submitter supplied) We identified the first Spt5-Pol II inhibitors (SPIs). SPIs faithfully reproduced Spt5 knockdown effects on proximal-promoter-pausing, NF-κB activation and the expanded-repeat huntingtin gene in neuronal cells. Using SPIs we identified Spt5 target genes that responded with profoundly diverse kinetics and a novel regulatory element of proximal-promoter-pausing. To validate that the effects of SPIs are at the transcriptional level, cellular RNA was metabolically labeled with 4-thio-uridine (4sU) for 2 hours in the presence of DMSO or SPI-21 in the presence or absence of TNFα. more...

Using SPIs we identified Spt5 target genes that responded with profoundly diverse kinetics and a novel regulatory element of proximal-promoter-pausing. To obtain a genome-wide view of the impact of SPIs on transcription, we performed Global run-on sequencing (GRO-seq) using nuclei of HeLa cells treated with either DMSO (control) or SPI-21.

(Submitter supplied) We identified the first Spt5-Pol II inhibitors (SPIs). SPIs faithfully reproduced Spt5 knockdown effects on proximal-promoter-pausing, NF-κB activation and the expanded-repeat huntingtin gene in neuronal cells. We determined the global effect of short and long-term SPI-21 treatment by RNA-seq and compared the affected genes between the two treatments. The results revealed that temporary and constitutive Spt5-regulated genes can be distinguished by SPIs.

(Submitter supplied) The pluripotency of embryonic stem cells (ESCs) relies on appropriate responsiveness to developmental cues. Promoter-proximal pausing of RNA polymerase II (Pol II) has been suggested to play a role in keeping genes poised for future activation. To identify the role of Pol II pausing in regulating ESC pluripotency, we have generated mouse ESCs carrying a mutation in the pause-inducing factor SPT5. Consistent with previous in vitro studies showing the pausing deficiency of this mutant SPT5, our genomic analysis reveals genome-wide reduction of paused Pol II in mutant mESCs. more...

(Submitter supplied) The regulation of gene expression by RNA polymerase II (Pol II) is a multistep process requiring the concerted action of diverse transcription factors. Very little is known about in vivo function of transcription factor SPT5 as its deletion results in loss of viability. To circumvent this issue and define in vivo mechanism of action for SPT5, we employed acute degradation of SPT5 and studied its consequence on transcription. more...

(Submitter supplied) The pause-release model of transcription proposes that pol II pauses 40-100 bases from the start site resulting in a pile-up that is relieved by subsequent release into productive elongation. Pause release is facilitated by PTEFb phosphorylation of the pol II elongation factor, Spt5. We mapped paused polymerases by eNETseq and found frequent pausing in zones that extend ~0.3-3kb into genes, even when PTEFb is inhibited. more...

(Submitter supplied) Many proteins associate with elongating RNA polymerase II (RNAPII), although the functions of most of them are still not well understood. Spt5 is an essential transcription elongation factor that binds directly to RNA polymerase and is conserved in prokaryotes, archaea, and eukaryotes1. In eukaryotes, evidence suggests that Spt5 functions in transcription elongation by both RNA polymerases I and II, mRNA capping, mRNA splicing, and mRNA 3’ end formation2. more...
