Additional Information

Thyroid Stimulating Hormone (TSH) is a heterodimeric glycoprotein hormone that regulates thyroid homeostasis upon interaction with the TSH receptor (TSHR). TSH binds to the TSH receptor, which couples preferentially to the G-alpha (s) (Gs) protein, resulting in activation of adenylate cyclase and increase in cyclic adenosine 3′, 5′ monophosphate (cAMP).
