Abstract:
Oligodendrocyte precursor cell (OPC) development into myelinated oligodendrocytes demands vigorous membrane addition. Since myristoylated alanine-rich C-kinase substrate (MARCKS) reportedly contributes to Ras-associated protein (Rab)-10-associated vesicle insertion into neuronal membranes, we investigated the role of MARCKS in OPC maturation. We found that either knockdown of MARCKS or interruption of its interaction with Rab10 would cause a decrease of the cell membrane area during OPC development. Enhanced MARCKS phosphorylation by Nogo66 or myelin debris treatment inhibited OPC maturation, while its dephosphorylation by protein phosphatase 2 A activator D-erythro-sphingosine promoted OPC development in the presence of myelin debris. Our results demonstrated that MARCKS is involved in OPC maturation by interacting with Rab10.
