== Function ==
[[http://www.uniprot.org/uniprot/VDR_RAT 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.<ref>PMID:17227670</ref>

== Publication Abstract from PubMed ==
The vitamin D receptor (VDR), a member of the nuclear receptor superfamily, functions as a ligand-dependent transcription factor for various genes. Hereditary vitamin D-resistant rickets (HVDRR), an autosomal recessive disease, is caused by mutations in the VDR. In particular, the missense mutations R274L and W286R in the ligand-binding domain of the VDR can severely reduce or even eliminate natural hormone responsiveness. Here, we report a crystal structure analysis of the R270L and W282R mutants of rat VDR (human R274L and W286R, respectively) in complex with the natural hormone and synthetic ligands. We also studied the folding properties of the mutant proteins by using circular dichroism spectra. Our study indicates that these mutations result in only local structural modifications. We discuss why these mutations disrupt the VDR function and provide clues to develop effective ligands for the treatment of HVDRR.
