Outline of Final Research Achievements

We analyzed the relationship between evolutionary conservation and function in O-GlcNAcylated proteins. The result of the multiple alignments of OGT/OGA was shown as a plot pattern. The phylogenetic analysis demonstrates that, OGT was widely　conserved in eukaryotes, but OGA was conserved only in animals. Additionally, in fungi and protists, OGT was conserved only in the catalytic domain. O-GlcNAcylated proteins were clustered into three classes, which called “Class 1”, “Class 2”, and “Class 3.”Class 1 with 47 proteins, conserved mainly in vertebrates.　That is, it is evolutionary “young” proteins. Class 2 with 94 proteins conserved in animals. Over half number of O-GlcNAcylated proteins belong to this class.Class 3 which 21 proteins widely conserved in eukaryotes.
