RAR (Retinoic Acid Receptor)
RAR, or Retinoic Acid Receptor, is a type of protein inside cells that helps control gene activity. It binds to retinoic acid, a form of vitamin A, and then attaches to specific DNA regions to regulate the production of proteins essential for processes like cell growth, development, and differentiation. RARs act as molecular switches, turning genes on or off in response to vitamin A signals, which is vital for normal development and maintaining health. Proper RAR function ensures cells grow and develop correctly, while malfunction can be linked to diseases like cancer.
