| Outline of Final Research Achievements |
In this study, we developed a novel chemical method to selectively label proteins expressed endogenously in live cells. Specifically, ligand-directed labeling reagents consisting of "N-acyl-N-alkylsulfonamide (NASA)" as a reactive group were developed. The NASA type labeling reagents were able to covalently modify the target protein more rapidly and efficiently than the conventional ligand directed chemistry. In addition, we successfully demonstrated that this method can selectively modify intracellular endogenous proteins, such as FKBP 12, eDHFR and Hsp90, with high efficiency.
