We are studying the consequences of activating mutations in the Leucine Rich Repeat Kinase 2 that underlie inherited Parkinson's disease, the second most common neurodegenerative disorder.  LRRK2 kinase phosphorylates Rab GTPases and we are studying how thie phosphorylation triggers cell biological changes in neurons and astrocytes.  We  discovered that Rab GTPase phosphorylation blocks primary cilia formation in cell culture and in specific brain regions.  Our approaches range from single molecule analysis of the membrane recruitment and activation of the kinase to understanding how loss of cilia in the dorsal striatum blocks Hedgehog signal sensing, leading to loss of dopaminergic neurons in the Substantia nigra and cholinergic neurons in the striatum.  We are seeking candidates with a background in biochemistry, cell biology or neurobiology to join our multidisciplinary efforts to understand the role of pathogenic LRRK2 kinase in Parkinson's disease at a molecular level.
