VDR Nuclear receptor for calcitriol, the active form of vitamin D3 which mediates the action of this vitamin on cells. Enters the nucleus upon vitamin D3 binding where it forms heterodimers with the retinoid X receptor/RXR. The VDR-RXR heterodimers bind to specific response elements on DNA and activate the transcription of vitamin D3-responsive target genes. Plays a central role in calcium homeostasis. Belongs to the nuclear hormone receptor family. NR1 subfamily. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
