[https://www.uniprot.org/uniprot/VDR_HUMAN VDR_HUMAN] Defects in VDR are the cause of rickets vitamin D-dependent type 2A (VDDR2A) [MIM:[https://omim.org/entry/277440 277440]. A disorder of vitamin D metabolism resulting in severe rickets, hypocalcemia and secondary hyperparathyroidism. Most patients have total alopecia in addition to rickets.<ref>PMID:2849209</ref> <ref>PMID:8381803</ref> <ref>PMID:1652893</ref> <ref>PMID:2177843</ref> <ref>PMID:8106618</ref> <ref>PMID:8392085</ref> <ref>PMID:7828346</ref> <ref>PMID:8675579</ref> <ref>PMID:8961271</ref> <ref>PMID:9005998</ref>

== 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 ==
The Vitamin D receptor (VDR) is a ligand-responsive transcription factor that forms homo- or heterodimers on response elements composed of two hexameric half-sites separated by three base pairs of spacer DNA. Binding of 1alpha,25-dihydroxyvitamin D(3) to the full-length VDR causes destabilization of the VDR homodimer and formation of a heterodimeric complex with the 9-cis retinoic acid receptor (RXR). VDR and RXR DNA-binding domains (DBDs) do not mimic this behavior, however: VDR DBD homodimers are formed exclusively, even in the presence of excess RXR DBD. Exploiting the asymmetry of the heterodimer and our knowledge of the homodimeric DBD interface, we have engineered VDR mutants that disfavor the homodimeric complex and allow for the formation of heterodimeric DBD complexes with RXR on DR3 elements. One of these complexes has been crystallized and its structure determined. However, the polarity of the proteins relative to the DNA is non-physiological due to crystal packing between symmetry-related VDR DBD protomers. This reveals a flattened energy landscape that appears to rely on elements outside of the core DBD for response element discrimination in the heterodimer.
