Ligand Dependent Switch from RXR Homo- to RXR-NURR1 Heterodimerization
Retinoid X receptors (RXRs) play key roles in many physiological processes in both the periphery and central nervous system. In addition, RXRs form heterodimers with other nuclear receptors to exert their physiological effects. The nuclear receptor related 1 protein (NURR1) is particularly interesting because of its role in promoting differentiation and survival of dopamine neurons. However, on...
متن کاملCAR2 Displays Unique Ligand Binding and RXR Heterodimerization Characteristics
The constitutive androstane receptor (CAR; NR1I3) regulates the expression of genes involved in xenobiotic metabolism. Alternative splicing of the human CAR gene yields an array of mRNAs that encode structurally diverse proteins. One form of CAR, termed CAR2, contains an additional four amino acids (SPTV) that are predicted to reshape the ligand-binding pocket. The current studies show a marked...
متن کاملA novel pathway for vitamin A signaling mediated by RXR heterodimerization with NGFI-B and NURR1.
In addition to its role as a 9-cis retinoic acid receptor, RXR has an important role in the regulation of multiple hormonal pathways through heterodimerization with nuclear receptors. Here, we show that two orphan receptors, NGFI-B and NURR1, which have been shown previously to interact with DNA as monomers, also can heterodimerize with RXR. These heterodimers bind selectively to a class of ret...
متن کاملAnalysis of RXR/THR and RXR/PPARG2 Heterodimerization by Bioluminescence Resonance Energy Transfer (BRET)
BACKGROUND Nuclear receptors (NR) regulate transcription of genes involved in many biological processes such as development, cell proliferation, differentiation and cell death. Amongst them, PPARG2 and THR control tissue glucose and lipid homeostasis which are deregulated in severe pathophysiological conditions such as metabolic syndromes. METHODOLOGY/PRINCIPAL FINDINGS Here, we describe a re...
متن کاملRetinoid X receptor (RXR) within the RXR-retinoic acid receptor heterodimer binds its ligand and enhances retinoid-dependent gene expression.
Retinoic acid receptor (RAR) and retinoid X receptor (RXR) form heterodimers and regulate retinoid-mediated gene expression. We studied binding of RXR- and RAR-selective ligands to the RXR-RAR heterodimer and subsequent transcription. In limited proteolysis analyses, both RXR and RAR in the heterodimer bound their respective ligands and underwent a conformational change in the presence of a ret...
