what results from the binding of tsh to its receptors
Thyrotropin receptor The thyrotropin receptor (or TSH receptor) is a receptor (and associated protein) that responds to thyroid-stimulating hormone (also known as "thyrotropin") and stimulates the production of thyroxine (T4) and triiodothyronine (T3). The TSH receptor is a member of the G protein-coupled receptor superfamily of integral membrane proteins[5] and is coupled to the Gs protein.[6]
Calcitonin Calcitonin (also known as thyrocalcitonin) is a 32-amino acid linear polypeptide hormone that is produced in humans primarily by the parafollicular cells (also known as C-cells) of the thyroid gland, and in many other animals in the ultimopharyngeal body.[3] It acts to reduce blood calcium (Ca2+), opposing the effects of parathyroid hormone (PTH).[4]
