The Parkinson disease causing LRRK2 mutation I2020T is associated with increased kinase activity
Open accessAbstract
Mutations in the leucine-rich repeat kinase 2 gene (LRRK2) have been recently identified in families with autosomal dominant late-onset Parkinson disease (PD). The LRRK2 protein consists of multiple domains and belongs to the Roco family, a novel group of the Ras/GTPase superfamily. Besides the GTPase (Roc) domain, it contains a predicted kinase domain, with homology to MAP kinase kinase kinases. Using cell fractionation and immunofluorescence microscopy, we show that LRRK2 is localized in the cytoplasm and is associated with cellular membrane structures. The purified LRRK2 protein demonstrates autokinase activity. The disease-associated I2020T mutant shows a significant increase in autophosphorylation of approximately 40% in comparison to wild-type protein in vitro. This suggests that the pathology of PD caused by the I2020T mutation is associated with an increase rather than a loss in LRRK2 kinase activity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
