(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...

(Submitter supplied) Transcript elongation by RNA polymerase II (RNAPII) is accompanied by conserved patterns of histone modification within transcribed regions, but it remains uncertain how these modifications influence, or are influenced by, properties of the elongation complex. Here we establish an intimate link between Cdk9, the kinase component of positive transcription elongation factor b (P-TEFb), and mono-ubiquitylation of histone H2B (H2Bub1), in the fission yeast Schizosaccharomyces pombe. more...

(Submitter supplied) The histone chaperone Spt6 is involved in promoting elongation of RNA polymerase II (RNAPII), maintaining chromatin structure, regulating co-transcriptional histone modifications, and controlling mRNA processing. These diverse functions of Spt6 are partly mediated through its interactions with RNAPII and other factors in the transcription elongation complex. In this study, we used mass spectrometry to characterize the differences in RNAPII interacting factors between wild-type cells and those depleted for Spt6, leading to the identification of proteins that depend on Spt6 for their interaction with RNAPII. 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 end of the RNA polymerase II (Pol II) transcription cycle is strictly regulated to ensure proper mRNA maturation and prevent interference between neighboring genes. Pol II slowing downstream of the cleavage and polyadenylation signal (CPS) leads to recruitment of cleavage and polyadenylation factors and termination, but how this chain of events is initiated remains unclear. In a chemical-genetic screen we identified protein phosphatase 1 (PP1) isoforms as substrates of human positive transcription elongation factor b (P-TEFb), the cyclin-dependent kinase 9 (Cdk9)-cyclin T1 complex. more...

(Submitter supplied) Histone H2B mono-ubiquitylation (H2Bub1) and phosphorylation of elongation factor Spt5 by cyclin-dependent kinase 9 (Cdk9) occur during transcription by RNA polymerase II (RNAPII), and are mutually dependent in fission yeast. How Cdk9 activity and H2Bub1 cooperate to regulate the expression of individual genes remains unclear. Here we show Cdk9 inhibition or H2Bub1 loss induces intragenic antisense transcription of distinct gene subsets; ablation of both pathways derepresses antisense transcription of over half the genome. more...

(Submitter supplied) Aim and Methods: To understand the precise role of Spt4 in budding yeast, various high throughput sequencing techniques were used. Nucleosome positions were studied using MNase-seq in WT and spt4∆ cells. The position of RNAPII was examined using NET-seq in spt4∆ cells or cells in which Spt4 has been anchored away to the cytoplasm (Spt4 AA). RNAPII was also mapped in cells in which Spt5 has been anchored away to the cytoplasm (Spt5 AA). more...

(Submitter supplied) At the end of protein-coding genes, RNA polymerase (Pol) II undergoes a concerted transition that involves 3’-processing of the pre-mRNA and transcription termination. Here we conduct a genome-wide analysis of this 3’-transition in yeast. We find that the 3’-transition globally requires the Pol II elongation factor Spt5 and factors involved in the recognition of the poly-adenylation (pA) site and in endonucleolytic RNA cleavage. more...
