  • with DUOX, are present at the apical membrane of thyrocytes
    • basic FUNCTION
  • thyroid peroxidase, thyroid hormone synthesis (iodide organification), and metabolism pathway
  • key enzyme in thyroid hormone production and a universal autoantigen in Graves' and other autoimmune thyroid diseases
  • at the apical membrane of thyrocytes, catalyzes thyroid hormone biosynthesis in the presence of H2O2 produced by DUOX1 and DUOX2

    small molecule metal binding,
  • binds 1 calcium ion per heterodimer
  • binds 1 heme B (iron-protoporphyrin IX) group covalently per heterodimer
    • protein
  • interacts with DUOX1, DUOX2 and CYBA
  • binding MPL and NUDC
  • TPO presents a catalase-like effect that protects DUOX1 and DUOX2 from inhibition by H2O2
