Genetically encoded protein photosensors 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. Here we report a method that increases the dynamic range of an artificial photoswitch based on the LOV2 domain of Avena sativa phototropin 1 (AsLOV2). This approach can potentially be used to improve many AsLOV2-based photoswitches.
