== 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 ==
Both 2alpha- and 2beta-hydroxypropyl substituted 14-epi-1alpha,25-dihydroxy-19-nortachysterols were synthesized to study the human vitamin D receptor (hVDR) binding affinity, binding configurations, and interactions with amino acid residues in the ligand binding domain of hVDR by X-ray co-crystallographic analysis. In conjunction with our previous results on 14-epi-19-nortachysterol, 2-methylidene-, 2alpha-methyl-, 2beta-methyl, and 2alpha-hydroxypropoxy-14-epi-19-nortachysterol, we propose a variety of effects of substitution at the C2 position in the 14-epi-19-nortachysterol skeleton on biological activities.

Effects of 2-substitution on 14-epi-19-nortachysterol-mediated biological events: based on synthesis and X-ray co-crystallographic analysis with the human vitamin D receptor.,Sawada D, Kakuda S, Takeuchi A, Kawagoe F, Takimoto-Kamimura M, Kittaka A Org Biomol Chem. 2018 Apr 4;16(14):2448-2455. doi: 10.1039/C8OB00158H.
