Myosin IIC: a third molecular motor driving neuronal dynamics.

ABSTRACT: Neuronal dynamics result from the integration of forces developed by molecular motors, especially conventional myosins. Myosin IIC is a recently discovered nonsarcomeric conventional myosin motor, the function of which is poorly understood, particularly in relation to the separate but coupled activities of its close homologues, myosins IIA and IIB, which participate in neuronal adhesion, outgrowth and retraction. To determine myosin IIC function, we have applied a comparative functional knockdown approach by using isoform-specific antisense oligodeoxyribonucleotides to deplete expression within neuronally derived cells. Myosin IIC was found to be critical for driving neuronal process outgrowth, a function that it shares with myosin IIB. Additionally, myosin IIC modulates neuronal cell adhe
