(Submitter supplied) The production of functional mRNA involves multiple steps including transcription initiation, elongation, and termination. spt5 encodes a conserved essential transcription elongation factor that controls RNAPII processivity in vitro and co-localizes with RNAPII in vivo. We used microarrays to detail the global expression of gene expression at 24 hours post fertilization in wild-type and Spt5 mutant (fog-sk8) to identify Spt5 transcriptionally dependent genes and affected pathways. more...

(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) The Spt4-Spt5 complex, and its human homolog DSIF (DRB sensitivity-inducing factor), is unique in its ability to regulate Pol II processivity. Previous studies have shown that Spt5 has the characteristics of a general transcription-elongation factor. However, mutagenesis of Spt5 showed specific phenotypes during development, which were far less severe than those of Pol II defects or TBP deficient embryos. 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) 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...
