Project description:Proteotoxic stress triggers adaptive cellular responses, including changes in gene expression on the levels of transcription and translation. In this study, we analyzed the translational response of yeast cells to impaired protein import into mitochondria, a condition under which mitochondrial precursor proteins accumulate in the cytosol and impose proteotoxic stress. We analyzed changes in translational efficiency as well as more subtle changes in the distribution of ribosomes along transcripts, with a special focus on translation initiation sites.
Project description:Stress responses to DNA damaging agents show characteristic responses. The effect of Azinomycin B upon cultured yeast cells in growth conditions appears to be significant. We used microarrays to detail the global programme of gene expression induced in the stress response to Azinomycin B. Keywords: stress response
