Protein: Thyroglobulin (F1RRV3)
Organism: Sus scrofa (Pig)
Function: Acts as a substrate for the production of iodinated thyroid hormones thyroxine (T4) and triiodothyronine (T3). The synthesis of T3 and T4 involves iodination of selected tyrosine residues of TG/thyroglobulin followed by their oxidative coupling. Following TG re-internalization and lysosomal-mediated proteolysis, T3 and T4 are released from the polypeptide backbone leading to their secretion into the bloodstream (By similarity). One dimer produces 7 thyroid hormone molecules (By similarity).
Subcellular location: Secreted {ECO:0000269|PubMed:12387814}. Note=Secreted into the follicular lumina of the thyroid (PubMed:12387814). Localizes to colloid globules, a structure formed in the thyroid follicle lumen consisting of cross-linked TG arranged in concentric layers (By similarity). {ECO:0000250|UniProtKB:P01266, ECO:0000269|PubMed:12387814}.
