Abstract
Compositions and methods for light controlled protein-protein interactions in a living cell. Two interacting PICL (protein interaction controlled by light) polypeptides are provided. The first polypeptide comprises an LOV (Light, Oxygen or Voltage) domain, which domain is a light sensor that uses flavin mononucleotide (FMN) as a chromophore. The second polypeptide, specifically interacts with the L polypeptide upon light activation of the LOV domain. One or both of the polypeptides are fused to a cellular protein of interest. Upon exposure to light, a targeted interaction between cellular proteins occurs. The ability to regulate protein-protein interactions with subcellular resolution using light is useful for controlling biochemical processes such transcription, receptor activation, protein degradation, synapse formation, etc. in cells and animals.
