<p>Chemical probe to catch N-phosphorylated protein have been developing and it is attractive way to figure out biological function of N-phosphorylation. I conducted reaearch about finding chemical probe of pLys and pAsp(althought it is not N-phosphorylation, it is also not stable) using antibody. This chemical approach to unstable phosphorylation is quite attractive but not easy. So I proposed another way to investigate the function of unstable non-canonical amino acids by developing tRNA and aminoacyl tRNA synthetase. If we can manage N-phosphorylated protein in organism, then it would be much easier, even after developing chemical probe for those amino acids, to conduct biological assay.</p>
