On YouTube: Floppy keys – how the communication in the cell works
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.
