GtoPdb	Measuring inhibition of LRRK2-mediated peptide substrate phosphorylation	-	7.3	pIC50	<50	nM	IC50	US11578061B2. Inhibitors of LRRK2 kinase (2023)
ChEMBL	LRRK2 Enzymatic Assay: LRRKtide substrate (peptide sequence RLGRDKYKTLRQIRQ, derived from human ezrin [amino acids 561-573], moesin [amino acids 539-553] and radixin [amino acids 558-570], obtained from SignalChem, catalogue #L10-58, reconstituted in 20 mM Tris-HCl at pH 7.5 to a final concentration of 1 mg/mL, assay concentration 20 μM) and recombinant human LRRK2 (catalytic domain only [amino acids 970-2527], GST-tagged, expressed in insect cells, obtained from ThermoFisher Scientific, catalogue #PV4874, 0.35 mg/mL, assay concentration 30 nM) were mixed in assay buffer (20 mM Hepes pH 7.5, 10 mM MgCl, 1 mM EGTA, 0.02% Brij35, 0.02 mg/ml BSA, 0.1 mM NaVO, 2 mM DTT, 1% DMSO). Compounds of interest (in DMSO, serial 3-fold dilution from 10 μM to 0.5 nM) or control (1% DMSO) were dispensed into the kinase reaction mixture by Acoustic technology (Echo550; nanoliter range). After incubation at room temperature for 20 minutes, the kinase reaction was initiated by addition of [P]-ATP (Specific activity 10 μCi/μl) and the mixture was incubated at room temperature for 2 hours. The reaction was then stopped by spotting the reaction mixture on strips of phosphocellulose P81 paper. Following washing, the radioactivity of the P81 paper was measured and kinase activity data were expressed as the percent remaining kinase activity in test samples compared to vehicle (dimethyl sulfoxide) reactions.
