| Outline of Final Research Achievements |
One of the methods to elucidate the biological function of glycan is to modify the expression of glycosyltransferases responsible for the biosynthesis of specific glycans and to analyze the phenotypes caused thereby. Moreover, to elucidate the relationship between glycan and biological function, glycosylated sites, glycan variation (glycome), and its proportions for each glycoprotein must be analyzed, if the determined glycan-carriers are of interest. Therefore, we developed a novel glycoproteomics technology to reveal the site-specific glycome in several glycan-modified cells/mice. As a result, we identified many carrier glycoproteins of the glycosyltransferase-specific glycans, including Lewis x, LacdiNAc, pLN and chondroitin sulfate structures, and tried to elucidate the molecules related to the phenotype and its molecular mechanism. Our novel glycoproteomics method provided important insights into the biological function of glycans.
