Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are a common cause of familial Parkinson's disease (PD). Variation around the LRRK2 locus also contributes to the risk of sporadic PD. The LRRK2 protein contains a central catalytic region, and pathogenic mutations cluster in the Ras of complex protein C terminus of Ras of complex protein (mutations(More)
A cluster of phosphorylation sites in LRRK2 (leucine-rich repeat kinase 2), including Ser910, Ser935, Ser955 and Ser973, is important for PD (Parkinson's disease) pathogenesis as several PD-linked LRRK2 mutants are dephosphorylated at these sites. LRRK2 is also dephosphorylated in cells after pharmacological inhibition of its kinase activity, which is(More)
Variation within and around the leucine-rich repeat kinase 2 (LRRK2) gene is associated with familial and sporadic Parkinson’s disease (PD). Here, we discuss the prevalence of LRRK2 substitutions in different populations and their association with PD, as well as molecular and cellular mechanisms of pathologically relevant LRRK2 mutations. Kinase activation(More)
Subpopulations of dopaminergic (DA) neurons within the substantia nigra pars compacta (SNpc) display a differential vulnerability to loss in Parkinson's disease (PD); however, it is not clear why these subsets are preferentially selected in PD-associated neurodegeneration. In rodent SNpc, DA neurons can be divided into two subpopulations based on the(More)
The complexity of the adult brain is a result of both developmental processes and experience-dependent circuit formation. One way to look at the differences between embryonic and adult brain is to examine gene expression. Previous studies have used microarrays to address this in a global manner. However, the transcriptome is more complex than gene(More)
Mutations in LRRK2 (leucine-rich repeat kinase 2) are the most common cause of familial PD (Parkinson's disease). Mutations that cause PD are found in either the GTPase or kinase domains of LRRK2 or an intervening sequence called the COR [C-terminus of ROC (Ras of complex proteins)] domain. As well as the two catalytic domains, LRRK2 possesses several(More)
LRRK2, a gene relevant to Parkinson's disease, encodes a scaffolding protein with both GTPase and kinase activities. LRRK2 protein is itself phosphorylated and therefore is subject to regulation by cell signalling; however, the kinase(s) responsible for this event have not been definitively identified. Here using an unbiased siRNA kinome screen, we identify(More)
In the period since LRRK2 (leucine-rich repeat kinase 2) was identified as a causal gene for late-onset autosomal dominant parkinsonism, a great deal of work has been aimed at understanding whether the LRRK2 protein might be a druggable target for Parkinson's disease (PD). As part of this effort, animal models have been developed to explore both the normal(More)

Supplementary Figure 1. Quality scores for RNA-Seq reads. The plot shows the mean Quality score, Q, on the y-axis for each base of all RNA-Seq reads per sample along the x-axis. Colors indicate individual animals as shown in the legend. Mean Q values stayed above 30 to the most 3ʼ base of the reads and the two groups of animals do not show obvious(More)
