维生素D受体(VDR)与类视黄醇X受体(RXR)作为专性异二聚体起作用。这些核受体(NR)是多结构域蛋白,目前尚不清楚不同结构域如何在NR异二聚体中相互作用。本研究表明,完整的异二聚体与DNA的结合改变了远离DNA结合域(DBDs)的区域的受体动力学,包括两种辅助受体的共激活因子结合表面,DNA响应元件的序列可以指定动力学。此外,激动剂与异源二聚体结合导致VDR DBD稳定性的变化,表明配体本身可能在DNA识别中发挥作用。这些数据提示了NR能够显示启动子特异性活性并对不同靶基因产生差异效应的机制,这为选择性NR调节剂的功能提供了机制见解。
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.
