Our laboratory is interested in the signal transduction events involving small GTPases of the Rho family, their regulators and effectors. These proteins play key roles in transducing extracellular stimuli into distinct responses including cell shape changes, cell motility, adhesion, cell division and phagocytosis. The emphasis of our current research is on the kinase PAK, its interacting protein PIX and a family of serine/threonine phosphataes of the PP2C family, POPXs.
