Thyroid peroxidase (TPO) is a heme-containing enzyme that is essential for the biosynthesis of thyroid hormones.{59768,59769} It exists as a homodimer where each monomer is composed of an extracellular N-terminal signal peptide and propeptide, an ectodomain containing MPO-, CCP-, and EGF-like domains, a transmembrane domain, and an intracellular C-terminal domain.{59769} TPO is regulated primarily at the transcriptional level by thyroid-stimulating hormone (TSH), which upregulates TPO expression. TPO is expressed by thyroid follicular cells and localizes to the apical plasma membrane in its active state.{59768,59769} It catalyzes the oxidation of iodine, resulting in the formation of monoiodotyrosine (MIT) and diiodotyrosine (DIT) residues on thyroglobulin, a protein that functions as a scaffold for thyroid hormone biosynthesis.{59771} TPO subsequently catalyzes the oxidative coupling between MIT and DIT residues on thyroglobulin to produce the thyroid hormones triiodothyronine (T3) and thyroxine (T4).{59771} Serum TPO autoantibodies are a hallmark of autoimmune thyroid diseases, including Hashimoto’s disease and Graves’ disease, and have been found in patients with breast cancer.{59770,59769} Cayman’s TPO (C-Term) Rabbit Monoclonal Antibody can be used for immunohistochemistry (IHC) and Western blot (WB) applications.
