Nuclear Receptors A Rendezvous for Chromatin Remodeling Factors
Nuclear receptors (NRs) are a large family of ligand-induced transcription factors that include the vitamin D receptor. The recent discovery of WINAC, a novel ATP-dependent chromatin remodeling complex, has shed new light on the molecular mechanisms by which the vitamin D receptor controls gene expression with unexpected clinical implications.
متن کاملNuclear receptors and chromatin: an inducible couple.
The nuclear receptor (NR) family comprises 48 transcription factors (TFs) with essential and diverse roles in development, metabolism and disease. Differently from other TFs, NRs engage with well-defined DNA-regulatory elements, mostly after ligand-induced structural changes. However, NR binding is not stochastic, and only a fraction of the cognate regulatory elements within the genome actively...
متن کاملLinking the ubiquitin-proteasome pathway to chromatin remodeling/modification by nuclear receptors.
Over 25 years ago, eukaryotic cells were shown to contain a highly specific system for the selective degradation of short-lived proteins, this system is known as the ubiquitin-proteasome pathway. In this pathway, proteins are targeted for degradation by covalent modification by a small highly conserved protein named ubiquitin. Ubiquitin-mediated degradation of regulatory proteins plays an impor...
متن کاملBile acids and gene regulation: from nuclear receptors to chromatin.
Transcription regulation by bile acids is far more complicated than it appeared at first when several groups began their investigations in the early '90. It has become clear now that bile acids regulate the transcription of genes involved in bile acid synthesis, transport and other metabolic pathways via multiple mechanisms that involve transcription factors, nuclear receptors, coregulators, ch...
متن کاملSWI/SNF-dependent chromatin remodeling of RNR3 requires TAF(II)s and the general transcription machinery.
Gene expression requires the recruitment of chromatin remodeling activities and general transcription factors (GTFs) to promoters. Whereas the role of activators in recruiting chromatin remodeling activities has been clearly demonstrated, the contributions of the transcription machinery have not been firmly established. Here we demonstrate that the remodeling of the RNR3 promoter requires a num...
