| Outline of Final Research Achievements |
BMP-1 has been well investigated as a catalytic enzyme of procollagen I-III and dentin-specific non-collagenous proteins; however, how BMP-1 affects cell surface molecules remains unclear. In this study, we focused on changes in glycan structure, ie, glycome-shift by BMP-1, which was clarified from a comprehensive analysis by lectin microarray in human dental pulp cells. We found that the N-acetylgalactosamine modification was slightly increased, while the α2,6-sialic acid modification was decreased in insoluble fractions from human dental pulp cells. These results suggest that BMP-1 is involved not only in the maturation of collagen and dentin-specific proteins as protease but also in glyco-alteration of membrane proteins in human dental pulp cells.
