Richard G. Fehon, PhD

The Fehon laboratory studies the organization and function of signaling pathway components at the cell cortex, particularly relating to the Hippo growth control pathway. In addition to their known role in organizing receptors and downstream effectors into functional signaling complexes, such organized complexes function to integrate signaling activities from multiple pathways and to segregate simultaneous but distinct functions of a single pathway. We study this question in Drosophila because of the utility of this system for studying the functions of individual genes, and for examining the functional interactions between different genes that work together in a particular cellular or developmental process.
