Role of LRRK2 in the regulation of dopamine receptor trafficking

Mutations in LRRK2 play a critical role in both familial and sporadic Parkinson’s disease (PD). Up to date, the role of LRRK2 in PD onset and progression remains largely unknown. However, experimental evidence highlights a critical role of LRRK2 in the control of vesicle trafficking that in turn may regulate different aspects of neuronal physiology. We have analyzed the role of...

GTPase activity regulates kinase activity and cellular phenotypes of Parkinson's disease-associated LRRK2

Mutations in the LRRK2 gene cause autosomal dominant Parkinson's disease. LRRK2 encodes a multi-domain protein containing a Ras-of-complex (Roc) GTPase domain, a C-terminal of Roc domain and a protein kinase domain. LRRK2 can function as a GTPase and protein kinase, although the interplay between these two enzymatic domains is poorly understood. Although guanine nucleotide...

LRRK2 Affects Vesicle Trafficking, Neurotransmitter Extracellular Level and Membrane Receptor Localization

The leucine-rich repeat kinase 2 (LRRK2) gene was found to play a role in the pathogenesis of both familial and sporadic Parkinson’s disease (PD). LRRK2 encodes a large multi-domain protein that is expressed in different tissues. To date, the physiological and pathological functions of LRRK2 are not clearly defined. In this study we have explored the role of LRRK2 in controlling...
