== Function ==
[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>

== Publication Abstract from PubMed ==
In the study of the synthesis of 14-epi-19-norprevitamin D(3), we found 14-epi-19-nortachysterol derivatives through C6,7-cis/trans isomerization. We also succeeded in their chemical synthesis and revealed their marked stability and potent VDR binding affinity. To the best of our knowledge, this is the first isolation of stable tachysterol analogues. Surprisingly, 14-epi-19-nortachysterol derivatives exhibited an unprecedented binding configurations for the ligand binding pocket in hVDR, C5,6-s-trans and C7,8-s-trans triene configurations, which were opposite the natural C7,8-ene-configuration of 1alpha,25(OH)(2)D(3).
