The 24th Sigrid Juselius Symposium


Hanasaari – The Swedish-Finnish Cultural Centre

Espoo, Finland,  June 10-13, 2011

Post-translational modifications (PTMs) modulate the activity of most eukaryotic proteins and are responsible for producing highly complex proteomes from relatively simple genomes. While the proteome-wide analysis of these modifications represents daunting challenges, this type of analysis will be critical to resolve the true functions of signal processing units in the cell. A major task of the cellular signaling machinery is to handle the multitude of stimuli that are related to various forms of developmental, stress, disease, or aging cues.

In the outlined symposium program, our goal is to exemplify by a selection of signaling systems how different PTM networks work together to control key processes in the cell. We also want to demonstrate that by deciphering these PTM networks important information can be obtained to understand the key signaling events underlying a broad spectrum of disease conditions ranging from immunological disorders and infectious diseases to cancer as well as aging and age-related diseases. Furthermore, the symposium will highlight how identification of critical nodes of these PTM networks can be employed for development of new therapies and drugs.

In summary, we believe that this interdisciplinary and integrating view of signaling is very timely. The speakers represent the absolute elite in their respective fields of research, many of them being founders or discoverers of the signaling systems or phenomena that they are about to describe. By bringing these experts together we also hope that we may reach a synergistic “enlightening” effect by the symposium that would be hard to achieve by any other means.
