Function

[VDR_RAT] Nuclear hormone receptor. Transcription factor that mediates the action of vitamin D3 by controlling the expression of hormone sensitive genes. Regulates transcription of hormone sensitive genes via its association with the WINAC complex, a chromatin-remodeling complex. Recruited to promoters via its interaction with the WINAC complex subunit BAZ1B/WSTF, which mediates the interaction with acetylated histones, an essential step for VDR-promoter association. Plays a central role in calcium homeostasis.[1] [MED1_HUMAN] Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors.[2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12]

Publication Abstract from PubMed

Non-secosteroidal ligands for vitamin D receptor (VDR) have been developed for the agonist with non-calcemic profiles. Here, we provide the structural mechanism of VDR agonism by novel non-secosteroidal ligands. All ligands had the similar efficacy, while two had the higher potency. Crystallographic analyses revealed that all ligands interacted with helix H10 and the loop between helices H6 and H7 in a similar manner, but also that the two ligands with higher potency had different interaction modes. This study suggests that distinct ligand potency depend upon differences in the formation and rearrangement of hydrogen-bond networks induced by each ligand.
