Thyroglobulin (TG) is a iodine-containing glycoprotein formed in the endoplasmic reticulum of thyrocytes and stored as colloid in thyroid follicles. TG consists of long chains with residuals of triiodothyronine (T3) and thyroxine (T4), from which the thyroid hormones T3 and T4 can be separated through stimulation by thyroid-stimulating hormone (TSH), if necessary.
