Light-activatable protein functions

We develop light-gated protein-protein interaction systems to control the activation and inactivation of intracellular signaling pathways. The ability to control signaling pathways by light offers unprecedented precision in temporal and spatial dimensions. Specifically, we are developing light-activatable molecular motors, light-activatable receptor tyrosine kinases, and light-activatable ERK and AKT signaling pathways.
