Abstract
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.
Claims9
An isolated nucleic acid molecule comprising a nucteotide sequence consisting of SEQ ID NO. 3 wherein the sequence encodes a functional NRIF3 nuclear hormone receptor co-activator polypeptide, wherein the NRIF3 binds in a ligand dependent manner to thyroid hormone receptor (TR) and retinoid X receptor (RXR), but does not interact with retinoic acid receptor (RAR), vitamin D receptor (VDR), progesterone receptor (PR), glucocorticoid receptor (GR), and estrogen receptor (ER) in a yeast two hybrid assay system or in vitro, or both, which polypeptide contains an LxxIL (SEQ ID NO:2) module in its C-terminal domain.
An isolated nucleic acid comprising a sequence that encodes an amino acid sequence consisting of SEQ ID NO:4 (FIG. 2).
An isolated nucleic acid sequence comprising a nucleotide sequence consisting of SEQ ID NO:3 (FIG. 2).
