Abstract
Rab GTPases are key regulators of vesicle-mediated transport and are proposed to play a crucial role in the pathobiology of Parkinson's disease. As membrane trafficking seems to be a relevant pathway altered in Parkinson' disease, understanding the role of Rab GTPases in the disease progression could open a window for therapeutic interventions. In this review, we focus on the recent advances on the role of Rab GTPases in the biology of two main proteins involved in Parkinson's disease: LRRK2 and α-synuclein, given that mutations in their genes (LRRK2 and SNCA) cause familial and sporadic Parkinson's disease.
