Description:

Thyrotropin Alfa

The product is a recombinant form of thyroid stimulating hormone. It is a heterodimeric glycoprotein comprised of two non-covalently linked subunits, an alpha subunit of 92 amino acid residues containing two N-linked glycosylation sites and a beta subunit of 112 residues containing one N-linked glycosylation site. The alpha subunit is nearly identical to that of human chorionic gonadotropin (hCG), luteinizing hormone (LH), and follicle-stimulating hormone (FSH). The alpha subunit is thought to be the effector region responsible for stimulation of adenylate cyclase (involved the generation of cAMP). The beta subunit (TSHB) is unique to TSH, and therefore determines its receptor specificity. The amino acid sequence of the product is identical to that of human pituitary thyroid stimulating hormone.
