We use molecular biology, biochemistry and cell biology to study the regulation of kinases that are activated by small GTP-binding proteins. We are particularly interested in the Raf protein kinases and the p21 activated protein kinases (PAKs) and have a special interest in the role that phosphorylation plays in their regulation. We have shown that Raf-1 and A-Raf require both serine and tyrosine phosphorylation for activation, whereas B-Raf requires only serine phosphorylation. We are examining how these phosphorylation events regulate Raf kinase activity and are attempting to identify the kinases that perform them.
