Neuronal migration from a germinal zone to a final laminar position is essential for the morphogenesis of neuronal circuits. While it is hypothesized that microtubule-actomyosin crosstalk is required for a neuron's 'two-stroke' nucleokinesis cycle， the molecular mechanisms controlling such crosstalk are not defined. By using the drebrin microtubule-actin crosslinking protein as an entry point into the cerebellar granule neuron system in combination with super-resolution microscopy， we investigate how these cytoskeletal systems interface during migration. Lattice light-sheet and structured illumination microscopy reveal a proximal leading process nanoscale architecture wherein f-actin and drebrin intervene between microtubules and the plasma membrane. Functional perturbations of drebrin demonstrate that proximal leading process microtubule-actomyosin coupling steers the direction of centrosome and somal migration， as well as the switch from tangential to radial migration. Finally， the Siah2 E3 ubiquitin ligase antagonizes drebrin function， suggesting a model for control of the microtubule-actomyosin interfaces during neuronal differentiation.
