Research Backgrounds


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 (By similarity).

Subcellular Location:

Nucleus. Cytoplasm.
Note: Localizes mainly to the nucleus (PubMed:28698609, PubMed:12145331). Localization to the nucleus is enhanced by vitamin D3.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Subunit Structure:

Homodimer in the absence of bound vitamin D3. Heterodimer with RXRA after vitamin D3 binding. Interacts with MED1, NCOA1, NCOA2, NCOA3 and NCOA6 coactivators, leading to a strong increase of transcription of target genes. Interacts with the corepressor NCOR1. Interacts with SNW1. Interacts with IRX4, the interaction does not affect its transactivation activity. Interacts with CRY1 (By similarity). Interacts with CRY2 in a ligand-dependent manner (By similarity).


Composed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal ligand-binding domain.

The 9aaTAD motif is a transactivation domain present in a large number of yeast and animal transcription factors.

Belongs to the nuclear hormone receptor family. NR1 subfamily.

Application: WB    Species: Mouse    Sample: brain

Fig. 7 Eriodictyol up-regulates VDR expression and activates the Nrf2/HO-1 signaling pathway. A VDR expression in the mouse brain was detected using immunohistochemical staining. Then, B the VDR protein expression level in the mouse cortex and hippocampus was measured using Western blotting. C The VDR protein expression level in HT-22 cells was measured using Western blotting, and D its relative mRNA expression level was detected using q-PCR. E The levels of Nrf2, p-Nrf2 and HO-1 in the mouse cortex and hippocampus were measured using Western blotting. F The levels of Nrf2, p-Nrf2 and HO-1 in HT-22 cells were measured using Western blotting. G The level of Nrf2 in the nucleus and cytoplasm of HT-22 cells was detected using Western blotting, and Lamin B1 and β-actin were used as loading controls for the nuclear and cytoplasmic proteins, respectively. The data are presented as the means ± SD of three experiments. **P < 0.01 and ***P < 0.001 compared with the Aβ1–42 oligomer group. ##P < 0.01 compared with the control group
