Optochemical genetics (OCG) merges small light-sensitive synthetic ligands with native or genetically engineered transmembrane proteins.
In this video, we demonstrate the interdisciplinary nature of our research by combining the chemical synthesis of our specifically tailored molecules with their application in a biological context. As an example, electrophysiological recordings are performed in an acute brain slice preparation. In this experiment, repeated illumination of a light-switchable glutamate derivative translates into light-dependent action potential firing.

Dirk Trauner currently resides as a Professor for Chemical Biology and Genetics at the Ludwig-Maximilians-Universität Munich. His research interests range from organic synthesis and natural products to chemical neurobiology and optochemical genetics.
Dr. Martin Sumser is the resident neuroscientist of the Trauner Group and thus responsible for the biological and electrophysiological research.
Matthias Schönberger is a graduate student interested in the design, synthesis and testing of photoswitchable ligands.
