Abstract

Members of the family of NEK kinases (NIMA related kinases) were identified as important regulators of cell cycle checkpoints, especially at the G2 to M phase transition. Although they are among all kinases one of the least studied families, recent studies showed they can have crucial roles in mitosis, centrosome disjunction, and in the signaling of the DNA damage response. These characteristics along with the fact that several NEKs were found to be over-expressed in cancer, or were shown to present elevated mutation rates, suggest that they are interesting candidates both in the diagnostic as well as in the therapy of cancer. However, for most NEKs the physiological substrates have not been identified and nor are the functional consequences of the found point mutations known that occur in their genes in cancer cells. Therefore, the central aim of this project is to elucidate the functional roles of the NEKs in normal and tumoral cells. We will use the "Shokat" approach to generate kinase that are sensitive to ATP analogs to identify physiological substrates of the NEKs. Furthermore, we will generate mutations observed in Nek genes in cancer tissues to analyze functional consequences of these altered kinases in vitro and in vivo. Furthermore, we will characterize the protein expression of NEKs in normal and tumor tissues and 'high throughput screening' of inhibitors, based on coupled kinase/luciferase ATP consumption bioassay, previously developed in our group. In summary, our project envisions to study the physiological and pathophysiological roles of NEK 1, 3, 4, 5, 6, 7, 8 and 10. The studies will contribute to explore the potential of these cell cycle regulatory kinases as novel targets in the therapy of cancer and envision the discovery of novel anti-cancer inhibitors. (AU)
