Summary of Meeting:
This meeting will focus on the control of signal transduction and cell cycle control by phosphorylation and posttranslational modifications, featuring pathways which are well studied and new mechanisms which are emerging. One aim is to report new concepts and discoveries on mechanisms for cellular regulation by signaling molecules, as well as creative approaches towards the design and development of highly specific inhibitors for these targets. Our goal is to provide investigators and students with a broad yet comprehesive understanding of new discoveries in this field using biochemical, structural and genetic strategies. A second aim is to promote novel experimental approaches for participants to use in their research. Plenary talks will highlight innovative strategies towards problems in signal transduction, including monitoring global cellular responses by genomics, proteomics and database mining, new strategies for protein engineering, and fluorescence based assays for monitoring signal transduction in single cells. A workshop will also be held on practical aspects of applying genomics, proteomics and bioinformatics to research problems. The meeting will be held jointly with a Keystone Symposium on "Wnt and Beta-catenin Signaling in Development and Disease", which discusses mechanisms by which the Wnt signaling pathway is regulated, ranging from basic research to clinical applications. Participants can choose between concurrent talks in each program, and two evening sessions will be held jointly, providiing a venue to learn perspectives at the forefront of each discipline, and to establish new contacts and collaborations.
