Previous GeneCards Identifiers for VDR Gene
This gene encodes vitamin D3 receptor, which is a member of the nuclear hormone receptor superfamily of ligand-inducible transcription factors. This receptor also functions as a receptor for the secondary bile acid, lithocholic acid. Downstream targets of vitamin D3 receptor are principally involved in mineral metabolism, though this receptor regulates a variety of other metabolic pathways, such as those involved in immune response and cancer. Mutations in this gene are associated with type II vitamin D-resistant rickets. A single nucleotide polymorphism in the initiation codon results in an alternate translation start site three codons downstream. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. A recent study provided evidence for translational readthrough in this gene, and expression of an additional C-terminally extended isoform via the use of an alternative in-frame translation termination codon.

GeneCards Summary for VDR Gene
VDR (Vitamin D Receptor) is a Protein Coding gene. Diseases associated with VDR include Vitamin D-Dependent Rickets, Type 2A and Rickets. Among its related pathways are Retinoic acid receptors-mediated signaling and Nuclear Receptors in Lipid Metabolism and Toxicity. Gene Ontology (GO) annotations related to this gene include DNA-binding transcription factor activity and steroid hormone receptor activity. An important paralog of this gene is NR1I2.
UniProtKB/Swiss-Prot Summary for VDR Gene
Nuclear receptor for calcitriol, the active form of vitamin D3 which mediates the action of this vitamin on cells (PubMed:28698609, PubMed:16913708, PubMed:15728261, PubMed:10678179). Enters the nucleus upon vitamin D3 binding where it forms heterodimers with the retinoid X receptor/RXR (PubMed:28698609). The VDR-RXR heterodimers bind to specific response elements on DNA and activate the transcription of vitamin D3-responsive target genes (PubMed:28698609). Plays a central role in calcium homeostasis (By similarity).
Vitamin D receptors (VDRs) are members of the NR1I family, which also includes pregnane X receptors (PXR) and constitutive androstane receptors (CAR). They form heterodimers with retinoid X receptor family members, and are expressed in the intestine, thyroid and kidney.
