Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene cause late-onset Parkinson's disease (PD). Emerging evidence suggests a role for LRRK2 in the endocytic pathway. Here, we show that LRRK2 is released in extracellular microvesicles (i.e. exosomes) from cells that natively express LRRK2. LRRK2 localizes to collecting duct epithelial cells in the(More)
Missense mutations in leucine-rich repeat kinase 2 (LRRK2) cause late-onset Parkinson's disease (PD), and common genetic variation in LRRK2 modifies susceptibility to Crohn's disease and leprosy. High levels of LRRK2 expression in peripheral monocytes and macrophages suggest a role for LRRK2 in these cells, yet little is known about LRRK2 expression and(More)
Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are the most common cause of autosomal dominant familial Parkinson's disease (PD) and also contribute to idiopathic PD. LRRK2 encodes a large multi-domain protein with GTPase and kinase activity. Initial data indicates that an intact functional GTPase domain is critically required for LRRK2 kinase(More)
Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are a common cause of autosomal dominant familial Parkinson's disease (PD). LRRK2 encodes a multi-domain protein containing GTPase and kinase enzymatic domains. Disease-associated mutations in LRRK2 variably influence enzymatic activity with the common G2019S variant leading to enhanced kinase(More)
Parkinson disease (PD) involves progressive neurodegeneration, including loss of dopamine (DA) neurons from the substantia nigra. Select genes associated with rare familial forms of PD function in cellular pathways, such as the ubiquitin-proteasome system (UPS), involved in protein degradation. The misfolding and accumulation of proteins, such as(More)
The detailed characterization of the function of leucine-rich repeat kinase 2 (LRRK2) may provide insight into the molecular basis of neurodegeneration in Parkinson's disease (PD) because mutations in LRRK2 cause a phenotype with strong overlap to typical late-onset disease and LRRK2 mutations are responsible for significant proportions of PD in some(More)
As genomics advances reveal the cancer gene landscape, a daunting task is to understand how these genes contribute to dysregulated oncogenic pathways. Integration of cancer genes into networks offers opportunities to reveal protein-protein interactions (PPIs) with functional and therapeutic significance. Here, we report the generation of a cancer-focused(More)
Discovery of effective drug combinations is a promising strategy to improve patient survival. This study explores the impact of heat shock protein 90 (Hsp90) inhibition in combination with focal adhesion kinase (FAK) inhibitor on the growth of non-small cell lung cancer cells (NSCLC cells). Our data show that 17-N-Allylamino-17-demethoxygeldanamycin(More)
Missense mutations in leucine-rich repeat kinase 2 (LRRK2) cause late-onset Parkinson's disease (PD), and common genetic variation in LRRK2 modifies susceptibility to Crohn's disease and leprosy. High levels of LRRK2 expression in peripheral monocytes and macro-phages suggest a role for LRRK2 in these cells, yet little is known about LRRK2 expression and(More)
