UniProt: Q5S007
Assay: Homogeneous Time Resolved-fluorescence Resonance Energy Transfer (TR-FRET) Assay: LRRK2 kinase activity is measured using a LanthaScreen kinase activity assay available from Invitrogen (Life Technologies Corporation). The assay is a homogeneous time resolved-fluorescence resonance energy transfer (TR-FRET) assay that measures phosphorylation of a fluorescein-labelled peptide substrate (fluorescein-LRRKtide, fluorescein-GAGRLGRDKYKTLRQIRQ) (SEQ ID NO 1) as a result of LRRK2 kinase activity. The phosphorylated peptide is recognized by a terbium-labelled phospho-specific anti-LRRKtide antibody and, subsequently, the phosphorylated LRRKtide can be quantified by the extent of TR-FRET between the terbium donor and fluorescein acceptor.The LRRK2 kinase is obtained from Invitrogen (Life Technologies Corporation) and comprises residues 970 to 2527 of the full length human wild-type LRRK2 kinase or a similar sequence with the G2019S mutation. As discussed above, this mutation increases the kinase activity relative to the wild-type. The kinase reactions are performed in a 20 uL volume in 384-well plates. The kinase reaction buffer consists of 50 mM Tris pH 8.5, 0.01% BRIJ-35, 10 mM MgCl2, 1 mM EGTA, and 2 mM DTT.Â  In the assay, 1 nM LRRK2 WT or 250 pM LRRK2 G2019S kinase is incubated with the test compound (typically at 0 to 30 uM) for 30 minutes before the kinase reaction is initiated by addition of 1.3 mM ATP and 0.4 uM fluorescein-LRRKtide. The reaction mixture (20 ul total volume) is incubated for 2 hours at 30° C. before the reaction is terminated by addition of 10 mM EDTA and 1 nM terbium-labelled anti-phospho-LRRKtide antibody (final volume 20 ul). The mixture is further incubated for 30 minutes at RT. TR-FRET is measured by excitation of the terbium-donor with 340 nm light and subsequent (delay time 100 us) measurement of terbium and fluorescein emission at 495 nm and 520 nm, respectively, over a time window of 1000 us. The measurement is repeated 10 times for fluorescein and 10 times for terbium emission with a 2000 us time window between repeats. TR-FRET measurements are performed on a Biomek Synergy plate. The TR-FRET signal is calculated as the emission-ratio at 520 nm over 495 nm.

It is estimated that FASN comprises about 25% of the cytosolic proteins in this cell line. SKBr3 cells were homogenized in a dounce homogenizer then centrifuged for 15 minutes at 4° C. to remove particulate matter. The supernatant was then analyzed for protein content, diluted to the appropriate concentration, and used to measure FASN activity. The presence of FASN was confirmed by western blot analysis. A similar method for isolation of FASN from SKBr3 cells is described in Teresa, P. et al. (Clin. Cancer Res. 2009; 15(24), 7608-7615). FASN activity of the SKBr3 cell extract was determined by measuring either NADPH oxidation or the amount of thiol-containing coenzyme A (CoA) released during the fatty acid synthase reaction. The dye CPM (7-diethylamino-3-(4'-maleimidyl-phenyl)-4-methylcoumarin) contains a thiol reactive group that increases its fluorescence emission on reaction with the sulfhydryl group of CoA.

Assay: In Vitro Assay: HEK 293 cells stably transfected with either Nav 1.7 or with Nav 1.5 were recorded in population patch-clamp mode with the IonWorks® Quattro automated electrophysiology system in accordance with the manufacturer's specifications (Molecular Devices, LLC, Sunnyvale, Calif.). Sodium channel currents were measured in response to a train of depolarizations that induced successively greater inactivation. Cells were held at −110 mV for three seconds (Nav 1.7) or half a second (Nav 1.5) from a holding voltage of −15 mV, then put through a series of 26 pulses of 150 msec duration to −20 mV at a frequency of 5 Hz. Cells were then left unclamped for a period of 3 to 8 minutes while a single concentration of test compound was added. Cells were then reclamped and put through the same voltage protocol. Current at the end of the 26th pulse to −20 mV was subtracted from the peak current evoked by the 26th pulse to −20 mV to correct for leak current.

Assay: ELISA-Based In Vitro Kinase Assay: GST-tagged recombinant wild-type or L1196M mutated ALK kinase (rALK) was expressed in Sf9 insect cells using the pBacPAK baculovirus vector system (Clontech) and purified using Glutathione Sepharose 4B affinity beads (GE Healthcare). Recombinant 3C protease was used to remove the GST tag. Purified ALK was used to screen inhibitors in the ELISA-based kinase assay, as follows: Nunc-Immuno 96-well plates were incubated overnight at 30° C. with coating solution containing 2 μg of a specific ALK peptide substrate (ARDIYRASFFRKGGCAMLPVK) in PBS. Wells were then washed with 200 μL of wash buffer (PBS-Tween 0.05%) and incubated with 4% BSA in PBS for at least 2 h at 30° C. The kinase reaction was performed in the presence of 50 mM Tris pH 7.5, 5 mM MnCl2, 5 mM MgCl2, 0.3 mM ATP and purified rALK in a total volume of 100 μL/well at 30° C. for 15 min. For inhibitor testing the reaction mix was preincubated with inhibitor or vehicle for 10 min at room temperature before transferring to the ELISA plate. After the reaction, the wells were washed 5 times with 200 μL of wash buffer. Phosphorylated peptide was detected using 100 μL/well of a mouse monoclonal anti-phosphotyrosine antibody (clone 4G10 UpstateBiotech Ltd) diluted 1:2000 in PBS+4% BSA. After 30 min incubation at room temperature the antibody was removed and wells were washed as described above. 100 μL of a secondary antibody (anti-mouse IgG, Horseradish Peroxidase linked whole antibody, Amersham Pharmacia Biotech) diluted 1:1000 in PBS+4% BSA was added to each well and the plate was incubated again for 30 min at room temperature before washing as above. The plate was developed using 100 μL/well TMB Substrate Solution (Pierce) and the reaction was stopped by adding an equal volume of 1M H2SO4. Finally, the absorbance was read at 450 nm using an ELISA plate reader (Bio-Rad).
