- Optical Manipulation of Subcellular Protein Translocation Using a Photoactivatable Covalent Labeling System
-
The photoactivatable chemically induced dimerization (photo-CID) technique for tag-fused proteins is one of the most promising methods for regulating subcellular protein translocations and protein–protein interactions. However, light-induced covalent protein dimerization in living cells has yet to be established, despite its various advantages. Herein, we developed a photoactivatable covalent protein-labeling technology by applying a caged ligand to the BL-tag system, a covalent protein labeling system that uses mutant β-lactamase. We further developed CBHD, a caged protein dimerizer, using caged BL-tag and HaloTag ligands, and achieved light-induced protein translocation from the cytoplasm to subcellular regions. In addition, this covalent photo-CID system enabled quick protein translocation to a laser-illuminated microregion. These results indicate that the covalent photo-CID system will expand the scope of CID applications in the optical manipulation of cellular functions.
