Requirements for heterodimerization between the orphan nuclear receptor Nurr1 and retinoid X receptors.
The nuclear receptor nurr1 is a transcription factor involved in the development and maintenance of neurons synthesizing the neurotransmitter dopamine. Although the lack of nurr1 expression has dramatic consequences for these cells either in terms of differentiation or survival, the mechanisms by which nurr1 controls gene transcription still remain unclear. In the intent to understand better th...
متن کاملRetinoid X receptors: common heterodimerization partners with distinct functions.
Retinoid X receptors (RXRs) have been implicated in a diversity of cellular processes ranging from cellular proliferation to lipid metabolism. These pleiotropic effects stem not only from the ability of RXRs to dimerize with diverse nuclear receptors, which exert transcriptional control on specific aspects of cell biology, but also because binding of RXR ligands to heterodimers can stimulate tr...
متن کاملSeparation of retinoid X receptor homo- and heterodimerization functions.
As a promiscuous dimerization partner the retinoid X receptor (RXR) can contribute to signaling by multiple nuclear receptors. However, the impact of RXR cosignaling and the possible existence of an RXR homodimer signaling pathway are largely unexplored. We report here on the separation of RXR homo- and heterodimerization as an essential step towards the elucidation of the roles of RXR homo- an...
متن کاملThe orphan nuclear receptor SHP inhibits hepatocyte nuclear factor 4 and retinoid X receptor transactivation: two mechanisms for repression.
The orphan nuclear hormone receptor SHP interacts with a number of other nuclear hormone receptors and inhibits their transcriptional activity. Several mechanisms have been suggested to account for this inhibition. Here we show that SHP inhibits transactivation by the orphan receptor hepatocyte nuclear factor 4 (HNF-4) and the retinoid X receptor (RXR) by at least two mechanisms. SHP interacts ...
متن کاملThe nuclear orphan receptor CAR-retinoid X receptor heterodimer activates the phenobarbital-responsive enhancer module of the CYP2B gene.
PBREM, the phenobarbital-responsive enhancer module of the cytochrome P-450 Cyp2b10 gene, contains two potential nuclear receptor binding sites, NR1 and NR2. Consistent with the finding that anti-retinoid X receptor (RXR) could supershift the NR1-nuclear protein complex, DNA affinity chromatography with NR1 oligonucleotides enriched the nuclear orphan receptor RXR from the hepatic nuclear extra...
