Role of R-loops and double R-loops in genome organisation and transcription. The majority of our genome is converted to an extensive network of non-protein-coding RNA molecules (ncRNAs), but the function of these ncRNAs is unknown. This project aims to identify and determine the mechanism of action of nuclear ncRNA networks with a particular focus on nuclear ncRNAs that form RNA-DNA hybrids with the genomic DNA. These studies have the potential to lead to ground-breaking discoveries in our under ....Role of R-loops and double R-loops in genome organisation and transcription. The majority of our genome is converted to an extensive network of non-protein-coding RNA molecules (ncRNAs), but the function of these ncRNAs is unknown. This project aims to identify and determine the mechanism of action of nuclear ncRNA networks with a particular focus on nuclear ncRNAs that form RNA-DNA hybrids with the genomic DNA. These studies have the potential to lead to ground-breaking discoveries in our understanding of genome organisation and the mechanism of transcription control, and might provide an entirely new tool-box to manipulate genome function. This should provide significant benefits to efforts to develop innovative biotechnology and genome editing technologies in plants and animals.Read moreRead less
RNA surveillance and the initial steps of RNA biogenesis. This project aims to understand the initial steps of RNA biogenesis and how this process is linked to the chromatin environment. Although less than five per cent of our genome encodes proteins, almost the entire genome is transcribed to RNA. A large portion of these transcripts are degraded during the early steps of RNA biogenesis by the RNA surveillance machinery, but the mechanism for the recognition and degradation of these transcripts ....RNA surveillance and the initial steps of RNA biogenesis. This project aims to understand the initial steps of RNA biogenesis and how this process is linked to the chromatin environment. Although less than five per cent of our genome encodes proteins, almost the entire genome is transcribed to RNA. A large portion of these transcripts are degraded during the early steps of RNA biogenesis by the RNA surveillance machinery, but the mechanism for the recognition and degradation of these transcripts is not understood. New evidence suggests that the chromatin environment of the transcribed locus plays an important role in this process. This project will lead to significant benefits in the implementation of emerging RNA-based technologies and in understanding how genome stability is maintained.Read moreRead less
Chromatin structure and pervasive transcription. This project aims to understand mechanisms that repress pervasive transcription and to identify chromatin characteristics that repress transcription initiation outside the promoter regions. Chromatin characteristics, such as position, occupancy and turnover-rate of nucleosomes, establish an elaborate genomic indexing mechanism, which defines functional units in the genome. Defects in this process increase pervasive transcription, toxic accumulatio ....Chromatin structure and pervasive transcription. This project aims to understand mechanisms that repress pervasive transcription and to identify chromatin characteristics that repress transcription initiation outside the promoter regions. Chromatin characteristics, such as position, occupancy and turnover-rate of nucleosomes, establish an elaborate genomic indexing mechanism, which defines functional units in the genome. Defects in this process increase pervasive transcription, toxic accumulation of non-coding transcripts and genomic instability. This work aims to understand eukaryotic genome organisation and may have long-term therapeutic implications for cancer and ageing-related diseases.Read moreRead less
Tracking factor footprints to reveal the intricacy and control of translation initiation. Messenger ribonucleic acid (RNA) translation is required for all of life and knowledge of how it works is central to modern life sciences. This project will develop novel ways of studying translation, generating entirely new descriptions of its inner workings that may transform knowledge of gene function and its use in medical and biotechnological processes.
