The vitamin D receptor (VDR) functions as an obligate heterodimer with the retinoid X receptor (RXR). These nuclear receptors (NRs) are multidomain proteins and it is unclear how various domains interact with one another within the NR heterodimer. Here we show that binding of intact heterodimer to DNA alters the receptor dynamics in regions remote from the DNA binding domains (DBDs), including the coactivator binding surfaces of both coreceptors, and the sequence of the DNA response element can specify the dynamics. Furthermore, agonist binding to the heterodimer results in changes in the stability of the VDR DBD, indicating that ligand itself may play a role in DNA recognition. These data suggest a mechanism by which NRs can display promoter-specific activity and impart differential effects on various target genes, which provides mechanistic insight for the function of selective NR modulators.
