I am working towards to design a study to asses the efficacy of different LRRK2 inhibitor compounds in neuron. I have been meaning to ask if there is any gold standard to check LRRK2 enzymatic activity.
Thank you
You may consider the detection of phosphorylation of LRRK2 substrates via immunoblotting:
1. Autophosphorylation at S1292
2. T73 Rab10 phosphorylation
3. to a lesser extent, T72 Rab8 phosphorylation
You may also consider Phostag assay for Rab10 phosphorylation, as published by the lab of Alessi doi: 10.1042/BCJ20160557
Good luck
Thank you for your answer
