The 2009 Gordon Research Conference on Phosphorylation and G Protein Signaling Networks will present cutting edge research on molecular mechanisms that underlie the action of many hormones, neurotransmitters, growth factors, and sensory stimuli. Organized sessions will discuss new research advances on the structure of G protein-coupled receptors (GPCR), regulation of GPCR, G protein-independent signaling of GPCR, G protein-regulating proteins, subcellular targeting of signaling proteins, G protein-regulated effectors, GPCR-promoted signaling into Ras-regulated networks, structural bases of G protein signaling, and drug discovery. The invited speakers apply biochemical, structural, cell biological, genetic, physiological, and therapeutic approaches to address mechanisms of cell signaling and their relationships to human disease and potential therapeutic interventions. The meeting will provide an excellent opportunity for junior scientists and graduate students to present their research in poster format and exchange ideas with leaders of the field. Approximately ten poster presenters will be selected for short talks. A collegial atmosphere, ample informal gatherings, and the programmed conference presentations and discussions will provide an ideal forum for exchange of ideas, development of cross-disciplinary collaborations, and immersion of young scientists in the process of scientific inquiry and discovery.
