Glossary Vitamin D Receptor

protein that binds vitamin D to regulate gene expression

The Vitamin D Receptor (VDR) is a protein found in various cells throughout the body that binds to vitamin D, allowing it to regulate the expression of specific genes. This receptor plays a crucial role in maintaining calcium and phosphate balance, which is essential for healthy bone formation, and it also influences immune system function and hair follicle cycling.
