Post-doc researcher, budding yeast transcriptomics and mitosis

Oslo, Norway

Post-doc position on the regulation mitotic transcription and chromatin architecture in S. cerevisiae

We announce a full-time postdoctoral position (36 months) in the group of Dr. Pierre Chymkowitch, Department of Microbiology, Oslo University Hospital, Oslo, Norway. The Dept. of Microbiology is a well-equipped internationally competitive research environment, and our group has an extensive collaboration network nationally and internationally. Finally, our research is interdisciplinary and has significant funding through the Research Council of Norway, Helse Sør Øst.

Project summary: The iconic X shape of condensed mitotic chromosomes has been described in the 19th century, but we still know little about the impact of mitotic condensation on chromatin functions like transcription. We have recently found that mitotic chromosome condensation is licensed by the centromere and spreads along chromosome arms in a chromosome-autonomous manner in S. cerevisiae (1). In parallel, other studies uncovered a mitotic-specific transcription program (2), but the molecular mechanisms establishing and maintaining mitotic transcription are yet unknown. This program seeks to uncover the mechanisms regulating mitotic transcription in the model organism S. cerevisiae. Based on other works and our preliminary data, we hypothesize that in addition to licensing chromatin condensation, centromeres control mitotic and interphase gene expression by impacting the transcription machinery. This project therefore seeks to identify new centromere functions and provide deeper insight into general mechanisms of gene expression and cell cycle regulation.
