Thyroid Peroxidase (TPO) also known as thyroperoxidase is an enzyme with a molecular mass of around 105 kDa. It is expressed in the thyroid gland's follicular cells. TPO plays a mechanical role in the synthesis of thyroid hormones by catalyzing iodination and coupling reactions needed to produce triiodothyronine (T3) and thyroxine (T4). These hormones are essential for regulating metabolism growth and development. The activity of TPO is an important step in thyroid hormone production.
Biological function summary

TPO participates in the thyroid's hormone biosynthesis pathway. It forms a part of the multi-enzyme complex that includes thyroglobulin and iodide. The enzyme facilitates the iodination of tyrosine residues on thyroglobulin and the coupling of iodotyrosines important for creating active thyroid hormones. TPO's enzymatic function is important for maintaining appropriate levels of circulating T3 and T4 impacting various physiological processes in the body.

Pathways

TPO contributes to the thyroid hormone synthesis pathway which is a critical pathway for metabolic regulation. It works in close association with other proteins such as thyroglobulin and sodium/iodide symporter (NIS) to ensure efficient thyroid hormone production. TPO's involvement in these pathways indicates its importance in the endocrine system's normal function and homeostasis.

TPO is often associated with autoimmune thyroid diseases like Hashimoto's thyroiditis and Graves' disease. High TPO antibodies such as anti-TPO antibodies are commonly detected in these conditions indicating an autoimmune response against the thyroid. The presence of high anti-thyroid peroxidase antibodies can lead to the destruction of thyroid tissue often resulting in hypothyroidism. TPO's connection to these diseases highlights its role in autoimmune conditions affecting thyroid function.
