FunctionIodination and coupling of the hormonogenic tyrosines in thyroglobulin to yield the thyroid hormones T(3) and T(4).
PathwayHormone biosynthesis; thyroid hormone biosynthesis.
Involvement in diseaseNote=An alternative splicing in the thyroperoxidase mRNA can cause Graves' disease.
Defects in TPO are the cause of congenital hypothyroidism due to dyshormonogenesis type 2A (CHDH2A) [MIM:274500]; also called genetic defect in thyroid hormonogenesis 2A or thyroid hormone organification defect II. CHDH2A is due to defective conversion of accumulated iodide to organically bound iodine. The iodide organification defect can be partial or complete.
Sequence similaritiesBelongs to the peroxidase family. XPO subfamily.
Contains 1 EGF-like domain.
Contains 1 Sushi (CCP/SCR) domain.
Heme is covalently bound through a H(2)O(2)-dependent autocatalytic process. Heme insertion is important for the delivery of protein at the cell surface.
Cleaved in its N-terminal part.
Cellular localizationMembrane and Cell surface.

Immunohistochemical staining of paraffin embedded human thyroid with purified ab133322 at a working dilution of 1 in 1000. The secondary antibody used is a HRP polymer for rabbit IgG. The sample is counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.
