The role of LRRK2 in cytoskeletal dynamics

Leucine-rich repeat kinase 2 (LRRK2), a complex kinase/GTPase mutated in Parkinson9s disease, has been shown to physically and functionally interact with cytoskeletal-related components in different brain cells. Neurons greatly rely on a functional cytoskeleton for many homeostatic processes such as local and long-distance vesicle transport, synaptic plasticity, and dendrites/axons growth and remodeling. Here, we will review the available data linking LRRK2 and the cytoskeleton, and discuss how this may be functionally relevant for the well-established roles of LRRK2 in intracellular trafficking pathways and outgrowth of neuronal processes in health and disease conditions.
