Inside cells, communication between the nucleus, which harbors our precious genetic material, and the cytoplasm is mediated by the constant exchange of thousands of signaling molecules and proteins. Until recently, it was unknown how this protein traffic can be so fast and yet precise enough to prevent the passage of unwanted molecules. Through a combination of computer simulations and various experimental techniques, researchers from the EMBL and the Heidelberg Institute of Theoretical Studies (HITS) have solved this puzzle: A very flexible and disordered protein can bind to its receptor within billionths of a second. Their research, led by Edward Lemke (EMBL), Frauke Gräter (HITS), was published in “Cell”.
This new Youtube clip was produced by the Cluster of Excellence CellNetworks with researchers from EMBL and HITS. The project was funded by Research in Germany/DFG. It shows how the binding of the “floppy key” proteins work.
About HITS
HITS, the Heidelberg Institute for Theoretical Studies, was established in 2010 by physicist and SAP co-founder Klaus Tschira (1940-2015) and the Klaus Tschira Foundation as a private, non-profit research institute. HITS conducts basic research in the natural, mathematical, and computer sciences. Major research directions include complex simulations across scales, making sense of data, and enabling science via computational research. Application areas range from molecular biology to astrophysics. An essential characteristic of the Institute is interdisciplinarity, implemented in numerous cross-group and cross-disciplinary projects. The base funding of HITS is provided by the Klaus Tschira Foundation.
