54 results about "Retinoid X receptor" patented technology

A polypeptide is identified as being functionally included in a signal transduction pathway having a biological effect. Contemplated polypeptides are different from a retinoic acid receptor, a retinoid X receptor, or a cellular retinoic acid binding protein, however bind a retinoid or retinoid metabolite, and binding of the retinoid or retinoid metabolite lead to a modulation of the biological effect. In particularly contemplated methods, a retinoid or retinoid metabolite is administered to a cell or mammal in a concentration effective to modulate the biological effect.

Disclosed is a compound represented by the general formula shown below, which can bind to a retinoid X receptor (RXR), which is one of nuclear receptors, and exhibit an agonistic or antagonistic action. [Wherein, R1 is selected from the group consisting of an alkyl group, an alkenyl group, an alkynyl group and an aryl group. R2 is selected from the group consisting of an alkoxy group, an alkyl group, an alkenyl group, an alkynyl group and an aryl group. W is NR3 or CR3; and R3 is selected from a hydrogen, an alkyl group, an alkenyl group, an alkynyl group and an aryl group. X1 and Y1 are selected from CH or N. X2 and Y2 are selected from CH, CR4 or N. R4 is selected from an alkyl group, an alkenyl group, an alkynyl group, an alkoxy group, a halogen, a nitro group and an amino group. Z is selected from a carboxylic acid, a carboxylate ester or a hydroxamic acid, which is bound directly or via an alkyl group, an alkenyl group or an alkynyl group.]

Nucleic acids encoding NRIF3 are described. Polypeptides having amino acid sequences of NRIF3 proteins are also provided. A method is also provided for isolating and cloning NRIF3 cDNA. NRIF3 is useful in development / implementation of high throughput screens to identify novel thyroid hormone receptor (TR) and retinoid X receptor (RXR) agonists and antagonists. Methods are also provided for identifying compounds that directly interfere with the interaction of NRIF3 and TR or RXR. Finally, therapies based on modulation of NRIF3 activity are disclosed.
