16.	ALA3705730	B	Binding Assay: Streptavidin (20 ul) (10 ug/ml Streptavidin type II (Wako Pure Chemical Industries, Ltd.), 10 mM Tris-HCl (pH 7.5), 10 mM NaCl) was added to a 384 well black plate (Nunc MaxiSorp, Thermo Fisher Scientific Inc.), and the plate was subjected to centrifugation (1000 rpm, 1 min) and coated overnight at 4 C. The plate was washed twice with PBST (PBS, 0.05% Tween 20, 100 ul/well) and blocked with 25% Block Ace (Snow Brand Milk Products Co., Ltd., PBS, 100 ul/well). The plate was subjected to centrifugation (1000 rpm, 1 min) and incubated at room temperature for 4 hr or overnight at 4 C. The plate was washed twice with PBST (PBS, 0.05% Tween 20, 100 ul/well), and biotinylate human TTR (stock solution concentration 1.0 mg/ml) diluted 750-fold with PBST was added at 20 ul/well. The plate was subjected to centrifugation (1000 rpm, 1 min) and stood still at room temperature for 1.5 hr or overnight at 4 C. The plate was washed 3 times with PBST (100 ul/well).

17.	ALA3889135	B	Scintillation Proximity Binding Assay: Untagged human RBP4 purified from urine of tubular proteinuria patients was purchased from Fitzgerald Industries International. It was biotinylated using the EZ-Link Sulfo-NHS-LC-Biotinylation kit from Pierce following the manufacturer's recommendations. Binding experiments were performed in 96-well plates (OptiPlate, PerkinElmer) in a final assay volume of 100 ul per well in SPA buffer (IX PBS, pH 7.4, 1 mM EDTA, 0.1% BSA, 0.5% CHAPS). The reaction mix contained 10 nM 3H-Retinol (48.7 Ci/mmol; PerkinElmer), 0.3 mg/well Streptavidin-PVT beads, 50 nM biotinylated RBP4 and a test compound. Nonspecific binding was determined in the presence of 20 uM of unlabeled retinol. The reaction mix was assembled in the dark under dim red light. The plates were sealed with clear tape (TopSeal-A: 96-well microplate, PerkinElmer), wrapped in the aluminum foil, and allowed to equilibrate 6 hours at room temperature followed by overnight incubation at +4° C. Radiocounts were measured using a TopCount NXT counter (Packard Instrument Company).	Homo sapiens	112	ALA3886957	single protein format	BindingDB Database
18.	ALA3889136	B	TR-FRET Assay: TR-FRET assay for retinol-induced RBP4-TTR interaction Binding of a desired RBP4 antagonist displaces retinol and induces hindrance for RBP4-TTR interaction resulting in the decreased FRET signal (FIG. 7). Bacterially expressed MBP-RBP4 and untagged TTR were used in this assay. For the use in the TR-FRET assay the maltose binding protein (MBP)-tagged human RBP4 fragment (amino acids 19-201) was expressed in the Gold(DE3)pLysS E. coli strain (Stratagene) using the pMAL-c4x vector. Following cell lysis, recombinant RBP4 was purified from the soluble fraction using the ACTA FPLC system (GE Healthcare) equipped with the 5-ml the MBP Trap HP column. Human untagged TTR was purchased from Calbiochem. Untagged TTR was labeled directly with Eu3+ Cryptate-NHS using the HTRF Cryptate Labeling kit from CisBio following the manufacturer's recommendations. HTRF assay was performed in white low volume 384 well plates (Greiner-Bio) in a final assay volume of 16 ul per well. The reaction buffer contained 10 mM Tris-HCl pH 7.5, 1 mM DTT, 0.05% NP-40, 0.05% Prionex, 6% glycerol, and 400 mM KF. Each reaction contained 60 nM MBP-RBP4 and 2 nM TTR-Eu along with 26.7 nM of anti-MBP antibody conjugated with d2 (Cisbio). Titration of test compounds in this assay was conducted in the presence of 1 uM retinol. All reactions were assembled in the dark under dim red light and incubated overnight at +4° C. wrapped in aluminum foil. TR-FRET signal was measured in the SpectraMax M5e Multimode Plate Reader (Molecular Device). Fluorescence was excited at 337 nm and two readings per well were taken: Reading 1 for time-gated energy transfer from Eu(K) to d2 (337 nm excitation, 668 nm emission, counting delay 75 microseconds, counting window 100 microseconds) and Reading 2 for Eu(K) time-gated fluorescence (337 nm excitation, 620 nm emission, counting delay 400 microseconds, counting window 400 microseconds).
