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

Hormone biosynthesis; thyroid hormone biosynthesis.

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.

Sequence similarities

Belongs to the peroxidase family. XPO subfamily.

Contains 1 EGF-like domain.

Contains 1 Sushi (CCP/SCR) domain.
