产品介绍
用作生产碘化甲状腺激素甲状腺素(T4)和三碘甲状腺素(T3)的底物。 T3和T4的合成涉及对TG /甲状腺球蛋白的选定酪氨酸残基加碘,然后在甲状腺滤泡内腔中进行氧化偶联。 在TG重新内在化和溶酶体介导的蛋白水解之后,T3和T4从多肽主链释放,导致它们分泌到血液中。 一个二聚体产生7个甲状腺激素分子。
背景资料
Thyroglobulin is the glycoprotein precursor of the iodinated thyroid hormones thyroxine (T4) and triiodothyronine (T3). Thyroglobulin is obtained from the thyroid gland and exhibits the general properties of the globulins. The human thyroglobulin (hTG) is a high molecular weight glycoprotein (605 kDa) found in the thyroid follicular cells. It plays a central role in the uptake, incorporation, and regulated biosynthesis of thyroid hormones, T4 and T3. Thyroid disorders are, in large part, due to autoimmune origin, and anti thyroglobulin autoantibodies were the first factor to be discovered. Anti hTG is found in all thyroid autoimmune diseases (Hashimoto's thyroiditis, Graves' diseases), with the highest level observed in Hashimoto's thyroiditis. Anti hTG is also characteristic of thyroid cancer, and its determination can be used for the follow up of cancer patients.
组织特异性
Thyroid gland specific.
翻译后修饰
Sulfated tyrosines are desulfated during iodination.
疾病
Defects in TG are the cause of thyroid dyshormonogenesis 3 (TDH3) [MIM:274700]. A disorder due to thyroid dyshormonogenesis, causing large goiters of elastic and soft consistency in the majority of patients. Although the degree of thyroid dysfunction varies considerably among patients with defective thyroglobulin synthesis, patients usually have a relatively high serum free triiodothyronine (T3) concentration with disproportionately low free tetraiodothyronine (T4) level. The maintenance of relatively high free T3 levels prevents profound tissue hypothyroidism except in brain and pituitary, which are dependent on T4 supply, resulting in neurologic and intellectual defects in some cases.
Variations in TG are associated with susceptibility to autoimmune thyroid disease type 3 (AITD3) [MIM:608175]. AITDs including Graves disease (GD) and Hashimoto thyroiditis (HT), are among the most common human autoimmune diseases. They are complex diseases, which are caused by an interaction between susceptibility genes and nongenetic factors, such as infection.
