The Weber laboratory utilizes tools of cell biology, protein chemistry and molecular biology to understand how signal transduction pathways control cell growth and apoptosis and how these controls are altered in cancer. A major focus of this research is on the MAP Kinase cascade, a ubiquitous signaling pathway that generates specific biological outcomes dependent on biological context. Recent findings of the lab have demonstrated an important role for "scaffolding proteins" that assemble components of the signaling cascades. They recently discovered the MORG1 scaffold protein (MAP Kinase Organizer) that regulates responses to LPA but not EGF. Signaling scaffolds can control the location, regulation, timing, substrates, biological functions, and suitability for therapeutic intervention of a signaling pathway.Â
