Genome-wide responses to stress.
Cells respond to stress conditions by launching complex gene expression programmes, both at the transcriptional and the post-transcriptional levels. The Mata Group is using the fission yeast, Schizosaccharomyces pombe, to investigate how cells remodel gene expression in response to stress, and to understand how these transcriptional and translational changes are coordinated. We concentrate on understanding how translation is remodelled during stress processes. We use methods such as ribosome profiling, which provides a high-resolution and genome-wide view of translation in normal cells and upon exposure to stress conditions. We are also very interested in how RNA-binding proteins regulate translation and how RNA stability varies during these processes. We have also started addressing these questions in other organisms, such as the plant pathogen Zymoseptoria tritici.
