Native Human Thyroglobulin Protein

Thyroglobulin (Tg) is a 660 kDa, dimeric protein produced by the follicular cells of the thyroid and used entirely within the thyroid gland. Thyroglobulin protein accounts for approximately half of the protein content of the thyroid gland. Human TG is a homodimer of subunits each containing 2768 amino acids as synthesized (a short signal peptide may be removed from the N-terminus in the mature protein) . Tg is used by the thyroid gland to produce the thyroid hormones thyroxine (T4) and triiodothyronine (T3) . Thyroglobulin has been shown to interact with Binding immunoglobulin protein.
