The Vitamin D Receptor

By January 19, 2023January 20th, 2023No Comments

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

In the nucleus, the VDR is usually phosphorylated in serine residues by a number of protein kinases. When ligand binding arises, the molecule triggers multiple intracellular signaling pathways that happen to be independent customer-x-pectations.com of the concentrate on gene transcription process.

The vitamin D receptor is a member of the superfamily of trans-acting transcriptional regulatory factors. It has a zinc finger DNA-binding domain, a ligand-binding website, and a transcriptional activation website. These elements are required for the protein’s functional activity.

The cDNA related to the vitamin D receptor was isolated coming from a human intestinal tract cDNA collection. RNA bare hybridization for the cDNA uncovered a single RNA species of about 4. six kb.

VDR expression is found in many cell types including epithelial cellular material, glial fibrillary acidic health proteins, dendritic cellular material, platelets, neutrophils, macrophages, and oligodendrocytes. Research using confocal microscopy have demonstrated VDR indivisible staining in several cellular nationalities.

Some research have looked at 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 genetic association studies have also revealed heterogeneity. This might be a result of invisible stratification within the populations examined.
