The Vitamin D Receptor

The calciferol receptor (VDR) is a trans-acting transcriptional regulating factor. It truly is expressed in the intestines, kidneys, skin, skeletal tissue, and a variety of defense cells. VDRs have been looked on to be a potential mechanism by which vitamin D influences calcium mineral absorption inside the gut, cell division, and bone cells maintenance.

In the nucleus, the VDR is normally phosphorylated upon serine residues by a amount of protein kinases. When ligand binding happens, the molecule triggers multiple intracellular signaling pathways which have been independent of the concentrate on gene transcription process.

The vitamin D receptor is a member of the superfamily of trans-acting transcriptional regulating factors. It contains a zinc finger DNA-binding domain, a ligand-binding website url, and a transcriptional service domains. These elements are essential for the protein’s useful activity.

The cDNA corresponding to the vitamin D receptor was isolated coming from a human intestinal tract cDNA library. RNA blot hybridization of the cDNA shown a single RNA species of about 4. six kb.

VDR expression is found in a variety of cell types which include epithelial skin cells, glial fibrillary acidic health proteins, dendritic skin cells, platelets, neutrophils, macrophages, and oligodendrocytes. Studies using confocal microscopy have demonstrated VDR elemental staining in several cellular ethnicities.

Some studies have explored the effects of VDR variants on osteoporosis and BMD. However , these studies have been limited in their sample size and have been inconclusive.

Meta-analyses of hereditary association studies have also revealed heterogeneity. This can be a result of hidden stratification in the populations researched.
