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] Evolutionary Conservation![]() Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedWe have successfully prepared E- and Z- isomers of 17-20 dehydro analogs of 2-methylene-19-nor-(20S)-1alpha,25-dihydroxyvitamin D3 (2MD). Both isomers bind to the recombinant rat vitamin D receptor (VDR) with high affinity. The Z-isomer (Vit-III 17-20Z) displays activity in vivo and in vitro that is similar to 2MD. The in vitro activity of the E-isomer (Vit-III 17-20E) is comparable to the natural hormone, though in vivo this analog is significantly less calcemic. Crystal structures of the rat VDR ligand binding domain complexed with the analogs demonstrate that the Vit-III 17-20Z analog is oriented almost identically to 2MD, with only minor differences induced by the planar configuration around the C17-C20 double bond. The Vit-III 17-20E analog is oriented in a conformation distinct from both 2MD and the natural hormone. The structural comparisons suggest that the position of C21 in the ligand binding site may be an important determinant of biological activity.
