thyroid hormone receptor

The thyroid hormone receptor is a protein inside cells that acts like a switch controlling how genes are turned on or off in response to thyroid hormones, mainly T3 and T4. When thyroid hormones bind to this receptor, it helps regulate many vital processes like metabolism, growth, and energy use. This receptor is mostly found in the cell nucleus, where it influences the activity of specific genes, ensuring the body functions properly. In essence, it serves as a crucial link between thyroid hormone signals and the genetic instructions that maintain health.
