Cognition emerges from the pattern forming activity of biochemical networks that execute cell signaling, and we are generally interested in how the dynamics of biochemical networks generate the spatial organization of signaling systems. Our attention is currently focused on the interdependence of membrane dynamics and early growth factor signal processing in cells. In this context, we investigate how the interaction of receptor tyrosine kinases (RTKs), small GTPases and Src family kinases with membrane systems affects the dynamics of signaling networks and thereby change the cell’s perception of the environment. Based on these studies, we opened new avenues for pharmacological interference with oncogenic signaling in cancer cells. We have also started a new synthetic biology research line in which we reconstitute from biochemical building blocks a trinity of signaling, cytoskeletal dynamics, and membrane shape that interact within a closed-loop causality to give rise to a self-organized morphogenic system.
