Project description:ZWC Complex-Mediated SPT5 Phosphorylation Suppresses Divergent Antisense RNA Transcription at the Active Gene Promoters

Project description:Purpose: The goals of this study are to understand the mechanistic roles of newly identified ZWC chromatin complex on the regulation of transcriptional process in actively transcribed genes. The novel ZWC complex is composed of ZC3H4, WDR82, and casein kinase II (CK2) subunits. Methods: Two biological replicates of ChIP-seq data for ZC3H4, WDR82, CK2, and SPT5 were generated from HEK293 cells. And one replicate of ChIP-seq data for RNAPII, H3K4me3, H3K27me3, and H3K36me3 was generated in HEK293 cells. Two biological replicates of ChIP-seq data were generated for RNAPII, S5p RNAPII, S2p RNAPII, SPT5, H3K4me3, H3K36me3, H3K27me3 after HEK293 cells were treated with control or ZC3H4 siRNAs. Results: The ZWC complex preferentially localizes at TSSs of active genes through the direct interactions of ZC3H4 and WDR82 subunits with S5p RNAPII CTD. ZC3H4 depletion leads to increased divergent antisense transcription. Conclusion: Our study provides evidence that the newly identified ZWC-DSIF axis regulates the direction of transcription during the transition from early to productive elongation

Project description:ZWC Complex-Mediated SPT5 Phosphorylation Suppresses Divergent Antisense RNA Transcription at the Active Gene Promoters [ChIP-Seq]

Project description:The human genome encodes large numbers of non-coding RNAs, including divergent antisense transcripts at transcription start sites (TSSs). However, molecular mechanisms by which divergent antisense transcription is regulated have not been detailed. Here, we report a novel ZWC complex composed of ZC3H4, WDR82 and CK2 that suppresses divergent antisense transcription. The ZWC complex preferentially localizes at TSSs of active genes through direct interactions of ZC3H4 and WDR82 subunits with the S5p RNAPII C-terminal domain. ZC3H4 depletion leads to increased divergent antisense transcription, especially at genes that naturally produce divergent antisense transcripts. We further demonstrate that the ZWC complex phosphorylates the previously uncharacterized N-terminal acidic domain of SPT5, a subunit of the transcription-elongation factor DSIF, and that this phosphorylation is responsible for suppressing divergent antisense transcription. Our study provides evidence that the newly identified ZWC-DSIF axis regulates the direction of transcription during the transition from early to productive elongation.

The novel ZWC complex is composed of ZC3H4, WDR82, and casein kinase II (CK2) subunits. Methods: Three biological replicates of RNA-seq data were generated after HEK293 cells were treated with control or ZC3H4 siRNAs. The RNA-Seq libraries were generated from 200 ng of total RNA using TruSeq Stranded Total RNA Library Prep kit (Illumina) according to the manufacturer's protocol. Results: The ZWC complex preferentially localizes at TSSs of active genes through the direct interactions of ZC3H4 and WDR82 subunits with S5p RNAPII CTD. ZC3H4 depletion leads to increased divergent antisense transcription.

Project description: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. However, the genome-wide requirement for Spt5 in transcription has not been extensively studied. To address this issue, we have comprehensively analyzed the consequences of Spt5 depletion on transcription by RNAPII in Schizosaccharomyces pombe using four genome-wide approaches: ChIP-seq, NET-seq, 4tU-seq, and RNA-seq. Our results demonstrate that, in the absence of Spt5, RNAPII accumulates at a high level over the first ~500 bp of transcription units, suggesting that Spt5 is globally required to elongate past a barrier to transcription. This possibility is strongly supported by results showing that Spt5 is required for a normal level of RNA synthesis. In addition to these effects on sense-strand transcription, Spt5 depletion results in widespread convergent antisense transcription that initiates at approximately the same position as the sense-strand barrier. While the role of these antisense transcripts is unknown, the two that were tested control the distribution of RNAPII. Our results also show that Spt5 represses divergent antisense transcription, explaining why it has not been previously observed in S. pombe. Taken together, our results reveal a global and critical role for Spt5 in multiple classes of transcription by RNAPII.
