What is the ligand for the vitamin D receptor?
The active form that is the ligand for the vitamin D receptor is calcitroic acid (or 1,25-dihydroxycholecalciferol or calcitriol).
What do vitamin D receptors do?
Vitamin D receptor (VDR) has been found in human skeletal muscle cells, where it affects muscle cell metabolism by binding to vitamin D metabolites. The VDR is involved in sustaining normocalcemia by inhibiting the production of parathyroid hormone and has effects on bone and skeletal muscle biology.
Does vitamin D bind to intracellular receptors?
The active form of vitamin D binds to intracellular receptors that then function as transcription factors to modulate gene expression.
Where is the vitamin D receptor?
In humans, the vitamin D receptor is encoded by the VDR gene located on chromosome 12q13. 11. VDR is expressed in most tissues of the body, and regulates transcription of genes involved in intestinal and renal transport of calcium and other minerals.
What does VDR stand for?

How does vitamin D pass through the cell membrane?
Lipid-soluble material with a low molecular weight can easily slip through the hydrophobic lipid core of the membrane. Substances such as the fat-soluble vitamins A, D, E, and K readily pass through the plasma membranes in the digestive tract and other tissues.
Do all cells have vitamin D receptors?
In higher-order animals, the vitamin D receptor (VDR) is found in nearly every cell, and the ability of the cell to produce the active hormone, 1,25(OH)2D, is also widely distributed.
What CDR means?
title noun. Cdr is the written abbreviation for Commander when it is used as a title.
What is VDR mutation?
Vitamin D-dependent rickets The VDR gene mutations that cause this condition prevent the VDR protein from functioning properly. Some changes in the VDR gene lead to an abnormally short version of the VDR protein. Others result in the production of an abnormal receptor that cannot bind to calcitriol, to RXR, or to DNA.
