The vitamin D receptor (VDR) is a trans-acting transcriptional regulatory factor. It is expressed in the intestines, kidneys, skin, bone tissue, and a variety of defense cells. VDRs have been deemed as being a potential mechanism by which calciferol influences calcium supplements absorption inside the gut, cell division, and bone cells maintenance.

Inside the nucleus, the VDR is certainly phosphorylated on serine elements by a amount of protein kinases. When ligand binding takes place, the molecule triggers multiple intracellular signaling pathways which can be independent of the concentrate on gene transcription process.

The vitamin D receptor is a member of the superfamily of trans-acting transcriptional regulatory factors. It includes a zinc finger DNA-binding domain, a ligand-binding website url, and a transcriptional service domain name. These elements will be required for the protein’s efficient activity.

The cDNA corresponding to the vitamin D receptor was isolated from a human intestinal cDNA selection. RNA mark hybridization with the cDNA explained a single RNA species of regarding 4. 6th kb.

VDR expression is found in various cell types which includes epithelial cellular material, glial fibrillary acidic proteins, dendritic skin cells, platelets, neutrophils, macrophages, and oligodendrocytes. Research using confocal microscopy have shown VDR indivisible staining in a number of cellular cultures.

Some research have looked at the effects of VDR variants upon osteoporosis and BMD. Nevertheless , these studies have been limited in their test size and have been inconclusive.

Meta-analyses of genetic association research have also found heterogeneity. This might be a result of concealed stratification for the populations learned.
