  • Product Description

    Thyrotropin-releasing hormone (TRH) is a tripeptide (L-pyroglutamyl-L-histidinyl-L-proline amide) that is released from the hypothalamus to stimulate release of thyroid-stimulating hormone from the thyrotropes of the anterior pituitary. In addition, TRH is synthesized in other regions of the CNS, where it appears to function as a neuromodulator to influence arousal, cognition, motor activity, depression, and food and water intake. TRH functions in the autonomic nervous system to modulate gastrointestinal motility and acid secretion (Nillni and Severino, 1999). The biological functions of TRH are mediated by binding to two Gq-coupled seven transmembrane receptors, TRH1 and TRH2 (Sun et al., 2003). TRH1 is present in humans, rodents, and other vertebrates, whereas TRH2 has been identified only in rodents. Synthetic TRH (protirelin) is used clinically to evaluate the functionality of the hypothalamic-pituitary-thyroid axis. The cloned human TRH-expressing cell line is made in the Chem-1 host, which supports high levels of recombinant TRH expression on the cell surface and contains high levels of the promiscuous G protein Gα15 to couple the receptor to the calcium signaling pathway. Thus, the cell line is an ideal tool for screening for antagonists of interactions between TRH and its ligands.
