PhD Thesis: Unravelling the role of CENP-A in DNA damage response

Diese Stellenanzeige ist abgelaufen. Finden Sie hier zahlreiche ähnliche Jobs.

The highly organized processes of cell division that take place at centromeric chromatin during mitosis and meiosis are still not fully understood. However, it is well known that instead of centromeric DNA sequences, epigenetic mechanisms regulate the formation at kinetochores at centromeres. The best-characterized epigenetic mark for centromeres is the histone H3-variant CENP-A, which replaces H3 in some of the nucleosomes within centromeric chromatin. We have recently shown that CENP-A reacts to DNA damage induction and unpublished results suggest that posttranslational modifications of CENP-A and other centromere-associated proteins are important for DNA–damage induced changes. This project is designed to uncover the relevance of changes in chromatin upon genotoxic stress for kinetochore formation, mitotic progression and faithful chromosome segregation. The projects involve a fast variety of biochemical, molecular and cell biological techniques, as well as high resolution, super resolution and live cell microscopy.
