Contributes to the organization of the actin cytoskeleton and cell shape (By similarity). Plays a role in the formation of lamellipodia and in cell migration (By similarity). Plays a role in the regulation of neuron morphology, axon growth and formation of neuronal growth cones, and may play a role in the regulation of neuronal spine density (By similarity). Plays a role in focal adhesion assembly and turnover (By similarity). Plays a role in intracellular protein transport and endocytosis, and in modulating the levels of potassium channels present at the cell membrane (By similarity).
