Parkinson's disease (PD) is the most common neurodegenerative movement disorder, with a prevalence of more than 1% after the age of 65 years. Mutations in the gene encoding leucine-rich repeat kinase-2 (LRRK2) have recently been linked to autosomal dominant, late-onset PD that is clinically indistinguishable from typical, idiopathic disease. LRRK2 is a multidomain protein containing several protein interaction motifs as well as dual enzymatic domains of GTPase and protein kinase activities. Disease-associated mutations are found throughout the multidomain structure of the protein. LRRK2, however, is unique among the PD-causing genes, because a missense mutation, G2019S, is a frequent determinant of not only familial but also sporadic PD. Thus, LRRK2 has emerged as a promising therapeutic target for combating PD. In this Mini-Review, we look at the current state of knowledge regarding the domain structure, amino acid substitutions, and potential functional roles of LRRK2.
