Regulation of the RNAPII Pool Is Integral to the DNA Damage Response [TT-seq]

Project description:In response to transcription-blocking DNA damage, cells orchestrate a multi-pronged reaction, involving transcription-coupled DNA repair, degradation of RNAPII and genome-wide transcription shutdown. How these responses are connected has remained unclear. Here we show that damage-induced ubiquitylation of RNAPII itself, at a single lysine (RPB1 K1268), is the focal point for DNA damage response coordination. K1268-ubiquitylation affects DNA repair and signals RNAPII degradation, essential for surviving genotoxic insult. It is also crucial for transcriptional shutdown, in the absence of which cells display dramatic transcriptome alterations. Additionally, regulation of RNAPII stability is central to transcription recovery – indeed, depletion of the RNAPII pool underlies the failure of this process in Cockayne syndrome B cells. These data expose regulation of global RNAPII levels as integral to the cellular DNA damage response, and open the intriguing possibility that RNAPII pool size generally affects cell-specific transcription programmes, in genome instability disorders and even normal cells.

Regulation of the RNAPII Pool Is Integral to the DNA Damage Response.

Project description:In response to transcription-blocking DNA damage, cells orchestrate a multi-pronged reaction, involving transcription-coupled DNA repair, degradation of RNA polymerase II (RNAPII), and genome-wide transcription shutdown. Here, we provide insight into how these responses are connected by the finding that ubiquitylation of RNAPII itself, at a single lysine (RPB1 K1268), is the focal point for DNA-damage-response coordination. K1268 ubiquitylation affects DNA repair and signals RNAPII degradation, essential for surviving genotoxic insult. RNAPII degradation results in a shutdown of transcriptional initiation, in the absence of which cells display dramatic transcriptome alterations. Additionally, regulation of RNAPII stability is central to transcription recovery-persistent RNAPII depletion underlies the failure of this process in Cockayne syndrome B cells. These data expose regulation of global RNAPII levels as integral to the cellular DNA-damage response and open the intriguing possibility that RNAPII pool size generally affects cell-specific transcription programs in genome instability disorders and even normal cells.

Disruption of RNAPII transcription elongation links Oncogenic splicing factor mutations to replciation stress and targetable alterations in chromatin landscape [TT-TL seq]

Project description:To investigate how whether the RNAPII defect is premature pause release defect or gene body elongation defect due to splicing factor mutations, we peformed TT-TL-seq (TT seq with a time lapse component) in K562 cells (wild type and SF3B1K700E mutant; U2AF1wild type vs U2AF1 S34F mutant) at 4 days after mutant allele expression We then performed metaplot-based and gene expression analysis using data obtained from TT-TL seq
