My laboratory is broadly interested in understanding the structural basis of signal transduction events that occur at the membrane surface. These events are mediated by signaling proteins that reversibly associate with membranes in response to binding second messengers, such as Ca2+ ions, diacylglycerol, and phosphoinositides. One of the key kinases regulating these signal transduction pathways is the Protein Kinase C (PKC) family. Aberrant levels of PKC expression or activity have been implicated in a large number of human diseases, such as cancer, cardiac failure, Alzheimer's disease, and diabetes. Despite the significance of PKC in signal transduction and human health, the structural and dynamical basis of its activation upon binding to lipid membranes remains elusive.
