Abstract

The cytoskeleton plays a key role in vital cellular processes like cell division and locomotion. It is a network composed of protein filaments which interact with a large number of different proteins. These regulate the assembly and disassembly of filaments and can cross-link them. Cross-links formed by motor proteins can be active as they are able to induce relative sliding of filaments and generate stresses in the filament network. In the talk, physical descriptions of cytoskeletal dynamics will be presented. They will be applied to different phenomena in living cells and in reconstituted systems. Notably, the Min-oscillations in the bacterium Escherichia coli, which are essential to determine the position of cell division, as well as the formation of contractile rings in dividing cells will be analyzed. Furthermore, a simple self-organized swimmer will be discussed.
