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