Perturbation of mRNP biogenesis reveals a dynamic landscape of the Rrp6-dependent surveillance machinery trafficking along the yeast genome (ChIP-seq dataset)

In order to dissect the nuclear RNA quality control (QC) mechanisms, we used a powerful assay based on global perturbation of mRNP biogenesis in yeast Saccharomyces cerevisiae by the bacterial Rho helicase. We have monitored the global RNA levels upon Rho activation and compare it to basal RNA level in WT strain, which have revealed down-regulated transcripts. Then, the same experiment was performed but in a strain lacking Rrp47, giving us a precise overview of the QC targets (crosslinked dataset). We also followed some QC components (Nrd1, Nab3, Trf4 and Rrp6) along the yeast chromosomes by ChIP-seq before (NI) and after (I) perturbation of mRNP biogenesis by Rho.
