Rab GTPases, the largest group of small monomeric GTPases, have been shown to participate in membrane trafficking involving many cellular processes. However, their roles during osteoblastic differentiation remain to be elucidated. In this study, we investigated Rab GTPase involvement in osteoblastic differentiation. Protein levels of a series of Rabs (Rab4, Rab5, Rab7, Rab9a, Rab11a/b, and Rab27) were increased during osteoblastic differentiation of MC3T3-E1 cells, and the Rab11a/b levels were particularly pronounced in the presence of Rho-associated coiled-coil-containing protein kinase (ROCK) inhibitor, an activator of osteoblastogenesis...
