Impact of Survivin Acetylation on its Biological Function

Angebote / Angebote:

In his research, David Dannheisig investigates the influence of lysine129 acetylation on the biological function of survivin including alteration of nucleocytoplasmic shuttling as well as dimerization behavior. Since survivin participates in two major hallmarks of oncogenesis, namely cell death inhibition and chromosomal segregation during the cell cycle, it reflects a valuable target in cancer therapy and research. The author establishes proximity-dependent, fluorescence-microscopic methods to quantify the interaction of survivin with the export receptor Crm1 as well as the homodimerization itself. In the future, those systems can be used to examine the feasible effect of chemical modulators which are targeting these interactions in a cellular background. The outcome achieved is an essential step towards the enhancement of potential cancer therapies. ContentsApoptosis – The Programmed SuicideCancer – The Enemy Inside Nucleocytoplasmic Transport– Cellular NavigationBiological Function of SurvivinProtein modification – Make-Up for ProteinsCell cycle – Virchow’s HeritageTarget GroupsLecturers, students and researchers in the biological-medical sectorPractitioners in the fields of molecular biology, cell biology, fluorescence microscopy, medical biology, protein interaction studiesThe AuthorDavid Dannheisig currently is a student of the International Graduate School in Molecular Medicine (IGradU) pursuing his PhD (Dr. rer. nat) degree at the Institute of Biochemistry and Molecular Biology (iBMB) at Ulm University, Germany.
