General annotation (Comments)
| Function | Iodination and coupling of the hormonogenic tyrosines in thyroglobulin to yield the thyroid hormones T3 and T4. |
| Catalytic activity | 2 iodide + H2O2 + 2 H+ = 2 iodine + 2 H2O. |
| Cofactor | Binds 1 calcium ion per heterodimer By similarity. Binds 1 heme B (iron-protoporphyrin IX) group covalently per heterodimer By similarity. |
| Pathway | |
| Subunit structure | Interacts with DUOX1, DUOX2 and CYBA By similarity. |
| Subcellular location | Membrane; Single-pass type I membrane protein By similarity. |
| Post-translational modification | Heme is covalently bound through a H2O(2)-dependent autocatalytic process. Heme insertion is important for the delivery of protein at the cell surface By similarity. Cleaved in its N-terminal part By similarity. N-glycosylated; contains mannose and N-acetylglucosamine. Ref.3 |
