Rationally improving LOV domain–based photoswitches

Genetically-encoded protein photosensors, including the LOV (light, oxygen, voltage) domain, are promising tools for engineering optical control of cellular behavior. We are only beginning to understand how to couple these light detectors to effectors of choice. We report a method that increases the...

Sumario:Genetically-encoded protein photosensors, including the LOV (light, oxygen, voltage) domain, are promising tools for engineering optical control of cellular behavior. We are only beginning to understand how to couple these light detectors to effectors of choice. We report a method that increases the dynamic range of an artificial photoswitch based on the LOV2 domain of A. sativa phototropin1 (AsLOV2). This approach can potentially be used to improve many AsLOV2-based photoswitches.
