== Function == | |||
[https://www.uniprot.org/uniprot/RXRA_HUMAN RXRA_HUMAN] Receptor for retinoic acid. Retinoic acid receptors bind as heterodimers to their target response elements in response to their ligands, all-trans or 9-cis retinoic acid, and regulate gene expression in various biological processes. The RAR/RXR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5. The high affinity ligand for RXRs is 9-cis retinoic acid. RXRA serves as a common heterodimeric partner for a number of nuclear receptors. The RXR/RAR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5. In the absence of ligand, the RXR-RAR heterodimers associate with a multiprotein complex containing transcription corepressors that induce histone acetylation, chromatin condensation and transcriptional suppression. On ligand binding, the corepressors dissociate from the receptors and associate with the coactivators leading to transcriptional activation. The RXRA/PPARA heterodimer is required for PPARA transcriptional activity on fatty acid oxidation genes such as ACOX1 and the P450 system genes.<ref>PMID:10195690</ref> <ref>PMID:11162439</ref> <ref>PMID:11915042</ref> <ref>PMID:20215566</ref> | |||

== Publication Abstract from PubMed == | |||
Rexinoids are ligands for the retinoid X receptor (RXR) that have great promise for both the prevention and treatment of cancer and metabolic diseases. In this regard, synthetic, functional, and structural investigations into the structure-activity relationships of derivatives of the potent RXR agonist (E)-3-[3-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydronaphthalen-2-yl)-4-hydro xyphenyl]acrylic acid (CD3254, 9) have been conducted. We recently reported on the characterization of a series of C3'-substituted alkyl ether analogues of 9 (10a-f), which display activities ranging from partial agonists to pure antagonists. The importance of the position of the alkoxy side chain for ligand activity has been further explored with the synthesis of C4'-substituted analogues (11a-f). Here we describe the synthesis of compounds 11a-f, which appear functionally different from their isomeric counterparts, as judged from transactivation assays and fluorescence anisotropy experiments. We also report on the 2.0 A resolution structure of RXR in complex with the parent compound 9, which helps understanding of the impact of the alkyl side chain location on ligand activity. | |||
