Adaptive signal processing

Dynamic protein–protein interactions are involved in most physiological processes and, in particular, for the formation of multiprotein signaling complexes at transmembrane receptors, adapter proteins and effector mole-cules. Because the unregulated induction of signaling complexes has sub-stantial clinical relevance, the investigation of these complexes is an active area of research.

In the central nervous system, long-term adaptive responses to changes in the environment, such as the processes involved in learning and memory, require the conversion of extracellular stimuli into intracellular signals. Many of these signals involve the induction of gene expression.
