Uncovering an evolutionary advanced mechanism of gene expression control. This project aims to uncover a new mechanism that activates gene expression in mammals, which involves unexpected connections between the core components of chromosomes and essential enzymatic machines required for the expression of genes.

This project aims to uncover a new mechanism that activates gene expression in mammals, which involves unexpected connections between the core components of chromosomes and essential enzymatic machines required for the expression of genes. This project will generate new knowledge on the poorly understood process of how the extensive genomic information of multicellular organisms is selectively chosen to enable the expression of only the required subset of genes. This will revolutionise our understanding of the mechanisms of gene control thereby shaping the field in the future. Significantly, this will allow new ways to manipulate gene expression that will impact biotechnology by providing new efficient ways to produce proteins or RNA. Read moreRead less
Nuclear RNA surveillance and its connection to splicing quality control. Due to the error-prone nature of RNA splicing, elaborate quality control processes ensure that only correctly spliced transcripts can leave the nucleus. It has long been known that incorrectly spliced mRNA transcripts are degraded by the nuclear RNA surveillance machinery, but how the RNA quality control machinery is connected to nuclear RNA surveillance is not known. This proposal aims to uncover the connection between the ....Nuclear RNA surveillance and its connection to splicing quality control. Due to the error-prone nature of RNA splicing, elaborate quality control processes ensure that only correctly spliced transcripts can leave the nucleus. It has long been known that incorrectly spliced mRNA transcripts are degraded by the nuclear RNA surveillance machinery, but how the RNA quality control machinery is connected to nuclear RNA surveillance is not known. This proposal aims to uncover the connection between these two important processes and will fill a significant gap in our understanding of how splicing quality control and nuclear RNA surveillance work. The project will also identify sequence features that trigger abortive splicing reactions and will thus help to improve the design of synthetic mRNAs.Read moreRead less
