DESCRIPTION

Also known as THYG_HUMAN, TG. Acts as a substrate for the production of iodinated thyroid hormones thyroxine (T4) and triiodothyronine (T3) (PubMed:32025030, PubMed:17532758). The synthesis of T3 and T4 involves iodination of selected tyrosine residues of TG/thyroglobulin followed by their oxidative coupling in the thyroid follicle lumen (PubMed:32025030). Following TG re-internalization and lysosomal-mediated proteolysis, T3 and T4 are released from the polypeptide backbone leading to their secretion into the bloodstream (PubMed:32025030). One dimer produces 7 thyroid hormone molecules (PubMed:32025030). Monomer (PubMed:32025030). Homodimer (via ChEL region); occurs in the endoplasmic reticulum and is required for export to the Golgi apparatus (PubMed:32025030). Homooligomer; disulfide-linked; stored in this form in the thyroid follicle lumen (PubMed:8626858).
