==Crystal structure of VDR ligand binding domain complexed to calcipotriol.==
-
The plethora of actions of 1alpha,25(OH)(2)D(3) in various systems, suggested wide clinical applications of vitamin D nuclear receptor (VDR), ligands in treatments of inflammation, dermatological indication, osteoporosis, cancers, and autoimmune diseases. More than 3000 vitamin D, analogues have been synthesized in order to reduce the calcemic side, effects while maintaining the transactivation potency of these ligands., Here, we report the crystal structures of VDR ligand binding domain bound, to two vitamin D agonists of therapeutical interest, calcipotriol and, seocalcitol, which are characterized by their side chain modifications., These structures show the conservation of the VDR structure and the, adaptation of the side chain anchored by hydroxyl moieties. The structure, of VDR-calcipotriol helps us to understand the structural basis for for, the switching of calcipotriol to a receptor antagonist by further side, chain modification. The VDR-seocalcitol structure, in comparison with the, structure of VDR-KH1060, a superagonist ligand closely related to, seocalcitol, shows adaptation of the D ring and position of C-21 in order, to adapt its more rigid side chain.

[https://www.uniprot.org/uniprot/VDR_HUMAN VDR_HUMAN] 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.<ref>PMID:16252006</ref> <ref>PMID:10678179</ref> <ref>PMID:15728261</ref> <ref>PMID:16913708</ref>
