05/2002The cover picture shows a model of an integrin-mediated signaling event. An intracellular protein binds to the integrin in the ground state (left). This leads to a conformational change, which exposes an extracellular binding site. Binding of a ligand on the extracellular site (middle) triggers a further conformational change, which in turn may be the starting point for an intracellular response (right). An X-ray structure of the activated form allowed modeling and docking studies of the ligand binding event. The computational studies demonstrate that the X-ray structure is only a snapshot in a multistage process. The new three-state model of integrin signaling is in agreement with biochemical data as well as other computational studies of the transmembrane domains. Further details can be found in the article by Kessler and co-workers on p. 470 ff.
