Len Stephens and Phill Hawkins are jointly responsible for a laboratory currently comprising 7 post-docs, 4 PhD students and 1 research technician. The programmes of work in the laboratory are currently aimed at understanding the molecular mechanisms and physiological significance of intracellular signalling networks which involve phosphoinositide 3OH-kinases (PI3Ks).
PI3Ks are now accepted to be critical regulators of numerous important and complex cell responses, including cell growth, division, survival and movement.
PI3Ks catalyse the formation of one or more critical phospholipid messenger molecules, which signal information by binding to specific domains in target proteins. Currently the best understood pathway involves the activation of Class I PI3Ks by cell surface receptors.
