Assay: AlphaScreen cAMP Assay: MIN6 cells [Miyazaki J et al. Endocrinology. 1990 July; 127(1):126-32] are stably transfected with an expression vector for human GPR119 cDNA (Acc. No. NP_848566). Min-6/hGPR119 cells are cultured in DMEM, 10% FBS, 50 uM β-mercaptoethanol, 0.3 mg/mL Geniticin, 2 mM GlutaMAX at 37° C. 5% CO2. For the assay, the cells are seeded in Optiplates (white, 384-well, 160W-barcoded, TC, sterile with lid, Cat. No. #6007688 (Perkin Elmer); 10000 cells/well; 50 ul). The plates covered with lids are then incubated for 24 hours at 37° C./5% CO2. After the medium is aspirated from the wells completely, 10 ul of the test compound are added, the compounds are diluted using stimulating buffer (140 mM NaCl, 3.6 mM KCl, 0.5 mM NaH2PO4, 0.5 mM MgSO4, 1.5 mM CaCl2, 10 mM Hepes, 5 mM NaHCO3; pH 7.4. 0.5 mM IBMX and 0.1% BSA, the final DMSO concentration is 1%). After 45 minutes incubation at room temperature (approx. 20° C.), the cAMP concentrations are determined using the AlphaScreen cAMP Assay Kit (Cat. No. #6760625R from PerkinElmer). 10 ul of Biotin-cAMP (final concentration 1 U/well in lysing buffer (5 mM Hepes (pH 7.4), 0.1% BSA, 0.5% Tween) and 10 uL Bead solution (final concentration 1 U/well in lysing buffer) are added. The plates are incubated for another 2 hours at room temperature. The cAMP concentrations are calculated using a cAMP standard curve from the Alpha Screen Counts. The data analysis is carried out by calculating the EC50 value and the maximum value based on a positive control, using suitable software (Graphpad Prism).

Target: Serine/threonine-protein kinase pim-1 (SINGLE PROTEIN), Homo sapiens
UniProt: P11309
Assay: Homogeneous Time Resolved Fluorescence Assay (HTRF): The assay for the determination of Pim activity is based on the formation of phosphorylated biotinylated-BAD peptide at the Serine 112 residue (S112) and employs HTRF® (homogeneous time resolved fluorescence) technology to detect the product in a 384-well plate format. The phosphorylation of biotinylated-BAD (S112) peptide by full length recombinant Pim-1, Pim-2, or Pim-3 protein was detected with streptavidin:Allophycocyanin (APC) conjugate and a europium (Eu) labeled antibody directed against phosphorylated-BAD (S112). Excitation of Eu by a high energy laser light (337 nm) leads to a transfer of energy to the APC molecule, and results in an emission at 665 nm. The fluorescence is directly proportional to the amount of phosphorylated BAD peptide present in the reaction. Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 22-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate [Costar 3658] in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The Reaction Buffer consisted of 45 mM Hepes, pH 7.0, 15 mM NaCl, and 1 mM MgCl. The quench/detection buffer consisted of 50 mM Tris, 100 mM NaCl, 0.05% BSA, 0.1% Tween and 3 mM EDTA. Biotinylated BAD peptide (Biopeptide), 10 mM ATP (Sigma), Labeled p-BAD (S112) mAb (Cell Signalling and Perkin Elmer) [with 0.05% BSA and 2 mM DTT added] streptavidin:Allophycocyanin [Perkin Elmer]. Final concentrations either Pim-1 enzyme [5 pM], or Pim-2 enzyme [0.5 pM], DMSO [1%], BLC BAD (S112) [0.5 μM], ATP [1.5 μM], streptavidin:Allophycocyanin [0.002 mg/mL] and biotinylated-BAD (S112) mAb [100 pM]. Initial incubations were carried out at RT (22° C.) for 30 min for both Pim-1 and for Pim-2. Pim enzyme is added to compound in buffer, and plates are incubated of 30 min. Biotinylated BAD and ATP are added and plates are incubated for 1 h. A mixture of labeled p-BAD (S112) mAb and quench/detection buffer are added and incubated for 2 h. Fluorescence was measured by an HTRF® Envision microplate reader.

Assay: Cellular Enzyme Assay: The expression plasmids contains the ORF for either human/cyno CYP11B1 or CYP11B2 under the control of a suitable promoter (CMV-promoter) and a suitable resistance marker (neomycin). Using standard techniques the expression plasmid is transfected into G-402 cells and these cells are then selected for expressing the given resistance markers. Individual cell-clones are then selected and assessed for displaying the desired enzymatic activity using 11-Deoxycorticosterone (Cyp11B2) or 11-Deoxycortisol (Cyp11B1) as a substrate. G-402 cells expressing CYP11 constructs were established as described above and maintained in McCoy's 5a Medium Modified, ATCC Catalog No. 30-2007 containing 10% FCS and 400 μg/ml G418 (Geneticin) at 37° C. under an atmosphere of 5% CO2/95% air. Cellular enzyme assays were performed in DMEM/F12 medium containing 2.5% charcoal treated FCS and appropriate concentration of substrate (0.3-10 μM 11-Deoxycorticosterone, 11-Deoxycortisol or Corticosterone). For assaying enzymatic activity, cells were plated onto 96 well plates and incubated for 16 h. An aliquot of the supernatant is then transferred and analyzed for the concentration of the expected product (Aldosterone for CYP11B2; Cortisol for CYP11B1). The concentrations of these steroids can be determined using HTRF assays from CisBio analyzing either Aldosterone or Cortisol.

Assay: Scintillation Proximity Assay (SPA): The binding of potential ligands to RORγ is measured by competition with [3H] 25-hydroxycholesterol (Perkin Elmer NET674250UC) using a scintillation proximity assay (SPA) binding assay. The ligand binding domain of human RORγ (A262-S507) with an N-terminal His tag is expressed in E. coli and purified using nickel affinity chromatography. 15 ug/well RORγ (A262-S507) is incubated with test compound at varying concentrations in 3-fold serial dilution, with final concentrations ranging from 16.6 uM to 0.28 nM for 10 min at room temperature in PBS buffer (Invitrogen #14190-144) containing 0.5% fatty acid free BSA (Gemini Bio-Products, Cat. #700-107P) and 0.1% Glycerol (Sigma Cat#G5516). 10 nM of [3H] 25-hydroxycholesterol is then added, and the reaction is incubated for 10 min. 10 mg/mL of Copper-His Tag-PVT beads (Perkin Elmer cat #RPNQ0095) are added, and the mixture is incubated for 60 min. The reaction is read on a TopCount Microplate scintillation plate reader (Perkin Elmer). The competition data of the test compound over a range of concentrations was plotted as percentage inhibition of radioligand specifically bound in the absence of test compound (percent of total signal). After correcting for non-specific binding, IC50 values were determined. The IC50 value is defined as the concentration of test compound needed to reduce [3H] 25-hydroxycholesterol specific binding by 50% and is calculated using the four parameter logistic equation to fit the normalized data.

Following a 2 mls per well wash with PBS-Tween-20, 100 μl of O-Phenylenediamine Dihydrochloride in phosphate-citrate buffer, containing urea hydrogen peroxide, was added to the wells for 7-10 minutes as a colorimetric substrate for the peroxidase. The reaction was terminated by the addition of 100 μl of 2.5N H2SO4 to each well and read using a microplate ELISA reader set at 492 nm.

Target: Kappa-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P41145
Assay: [35S]GTPγS Functional Assay: Functional [35S]GTPγS binding assays were conducted as follows. κ opioid receptor membrane solution was prepared by sequentially adding final concentrations of 0.026 μg/μl κ membrane protein (in-house), 10 μg/mL saponin, 3 μM GDP and 0.20 nM [35S]GTPγS to binding buffer (100 mM NaCl, 10 mM MgCl2, 20 mM HEPES, pH 7.4) on ice. The prepared membrane solution (190 μl/well) was transferred to 96-shallow well polypropylene plates containing 10 μl of 20× concentrated stock solutions of agonist prepared in DMSO. Plates were incubated for 30 min at a temperature of about 25° C. with shaking. Reactions were terminated by rapid filtration onto 96-well Unifilter GF/B filter plates (Perkin Elmer, Shelton, Conn.) using a 96-well tissue harvester (Packard) and followed by three filtration washes with 200 μl ice-cold binding buffer (10 mM NaH2PO4, 10 mM Na2HPO4, pH 7.4). Filter plates were subsequently dried at 50° C. for 2-3 hours. Fifty μl/well scintillation cocktail (Perkin Elmer, Shelton, Conn.) was added and plates were counted in a Packard Top-Count for 1 min/well.

UniProt: P56524
Assay: Two-Hybrid Assay: Detection of MEF2D and HDAC4 interactions. In this mammalian two-hybrid assay, HDAC4 and MEF2D proteins were used as representative members of their respective protein families because the protein-protein interactions involved in the recruitment of class IIa HDACs by MEF2 were highly conserved. Two separate DNA constructs were made with MEF2D fused with the GAL4 DNA binding domain (GAL4-MEF2D) and with the MEF2-binding motif of HDAC4 (AA 155-220) fused with the viral transactivator VP-16 (HDAC4-VP16) (FIG. 1). Human epithelial carcinoma cells (HeLa) were co-transfected with the two DNA constructs (GAL4-MEF2D and HDAC4-VP16) and a reporter plasmid (Gal4Luc). The DNA constructs resulted in expression of the GAL4-MEF2D and HDAC4-VP16 fusion proteins within the cell. MEF2D and HDAC4 protein interactions were detected as a result of the GAL4-MEF2D and HDAC4-VP16 protein complex binding a DNA promoter on the reporter plasmid (Gal4Luc) and driving cellular expression of a luciferase gene.
