TSHR is activated by the [https://en.wikipedia.org/wiki/Thyroid-stimulating_hormone Thyroid Stimulating Hormone (TSH)] also known as thyrotropin. Activation of TSHR initiates a signaling pathway for the production of thyroid hormones such as [https://en.wikipedia.org/wiki/Triiodothyronine T<sub>3</sub>] and [https://en.wikipedia.org/wiki/Thyroid_hormones T<sub>4</sub>] (Fig 1). These hormones are used to regulate the metabolism. | ||
