| Outline of Final Research Achievements |
Post-phosphoryl sugar chain is associated with muscular dystrophy and brain malformation and thus is believed to play important physiological roles. However, its structure, modification mechanism, and physiological functions are remained to be elucidated. In this study, we identified tandemly connected ribitol-phosphate, a novel post-modification unit in mammals, as a substance of post-phosphoryl modification. We also identified four enzymes involved in the biosynthesis of ribitol-phosphate modification. These enzymes are encoded by genes responsible for muscular dystrophy. Furthermore, we generated model mice for ribitol-phosphate deficiency and revealed pathomechamism of brain abnormality in muscular dystrophy patients, leading to a proposal of novel therapeutic strategies.
