-
A recombinant form of the heterodimeric human anterior pituitary glycoprotein thyroid-stimulating hormone (TSH) with potential use in hormone replacement therapy. Recombinant TSH binds to TSH receptors on thyroid epithelial cells and stimulates TSH-dependent signaling pathways. This stimulates iodine uptake and organification, and induces synthesis and secretion of thyroglobulin (Tg), triiodothyronine (T3), and thyroxine (T4).
