Optochemical Biology - In-situ Assembly of Macromolecular Complexes Triggered by Light

Chemical and synthetic biology aims for a perfect control of cellular networks in time and space by site-specific labeling, manipulation, and structured organization of protein complexes. This seminar will summarize recent developments using generic interaction pairs, which can be triggered by light. Multiplexed assembly of protein complexes is realized by iterative in situ activation, writing and binding processes via scanning laser microscopy. These light-triggered recognition processes allow for a spatiotemporal control of protein-protein interactions and rewiring cellular pathways. Approaches how to trigger protein complexes in three dimensions are discussed.
