Methods that allow labeling and tracking of proteins have been instrumental for understanding their function. Traditional methods for labeling proteins include fusion to fluorescent proteins or self-labeling chemical tagging systems such as SNAP-tag or Halo-tag. These latter approaches allow bright fluorophores or other chemical moieties to be attached to a protein of interest though a small fusion tag. In this work, we sought to improve the versatility of self-labeling chemical-tagging systems by regulating their activity with light. We used light-inducible dimerizers to reconstitute a split SNAP-tag (modified human O6-alkylguanine-DNA-alkyltransferase, hAGT) protein, allowing tight light-dependent control of chemical labeling. In addition, we generated a small split SNAP-tag fragment that can efficiently self-assemble with its complement fragment, allowing high labeling efficacy with a small tag. We envision these tools will extend the versatility and utility of the SNAP-tag chemical system for protein labeling applications.
