| Enzyme Function | FUNCTION: Acts as a substrate for the production of iodinated thyroid hormones thyroxine (T4) and triiodothyronine (T3) (By similarity). The synthesis of T3 and T4 involves iodination of selected tyrosine residues of TG/thyroglobulin followed by their oxidative coupling (By similarity). Following TG re-internalization and lysosomal-mediated proteolysis, T3 and T4 are released from the polypeptide backbone leading to their secretion into the bloodstream (Probable). One dimer produces 7 thyroid hormone molecules (By similarity). {ECO:0000250|UniProtKB:F1RRV3, ECO:0000250|UniProtKB:P01266, ECO:0000305|PubMed:12782676}. |

| Post Translational Modification | PTM: Iodinated on tyrosine residues by TPO (By similarity). There are 4 pairs of iodinated tyrosines used for coupling: acceptor Tyr-25 is coupled to donor Tyr-150 or Tyr-235, acceptor Tyr-2572 is coupled to donor Tyr-2539, acceptor Tyr-2764 in monomer 1 is coupled to donor Tyr-2764 in monomer 2 and acceptor Tyr-1310 in monomer 1 is coupled to donor Tyr-109 in monomer 2 (By similarity). {ECO:0000250|UniProtKB:F1RRV3, ECO:0000250|UniProtKB:P01266}.; PTM: Sulfated tyrosines are desulfated during iodination. {ECO:0000250|UniProtKB:P01266}.; PTM: Undergoes sequential proteolysis by cathepsins to release thyroxine (T4) and triiodothyronine (T3) hormones (PubMed:12782676). In the thyroid follicle lumen, cross-linked TG (storage form) is solubilized by limited proteolysis mediated by cathepsins CTSB and/or CTSL (PubMed:12782676). Partially cleaved TG is further processed by CTSK/cathepsin K and/or CTSL resulting in the release of T4 (PubMed:12782676). Following endocytosis, further processing occurs leading to the release of T3 and more T4 hormones (Probable). {ECO:0000269|PubMed:12782676, ECO:0000305|PubMed:12782676}. |
