Thyroid Stimulating Hormone Receptor (TSHR)

The thyrotropin receptor is a protein 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.It is primarily found on the surface of the thyroid epithelial cells.It should not be confused with "thyrotropin-releasing hormone" (TRH) or "thyrotropin-releasing hormone receptor" (TRHR).The deduced 764-amino acid protein has a molecular mass of 86.8 kD and contains a signal peptide, 7 transmembrane regions, 5 potential glycosylation sites, and a short intracytoplasmic region. The TSHR cDNA encoded a functional receptor that activated adenylate cyclase in response to TSH.
