Comprehensive study of nuclear receptor DNA binding provides a revised framework for understanding receptor specificity

Abstract

The type II nuclear receptors (NRs) and the retinoid X receptor (RXR) form heterodimeric transcription factors to regulate development, metabolism, and inflammation. Here the authors employ protein-binding microarrays to comprehensively analyze the DNA binding of 12 NR:RXRα heterodimers, and report promiscuous NR-DNA binding.
