General function:
Involved in calcium ion binding
Specific function:
Iodination and coupling of the hormonogenic tyrosines in thyroglobulin to yield the thyroid hormones T(3) and T(4).

I(-) + 3,5-Diiodo-L-tyrosine → Iodotyrosine + Iodinedetails
General function:
Involved in thyroxine 5'-deiodinase activity
Specific function:
Responsible for the deiodination of T4 (3,5,3',5'-tetraiodothyronine) into T3 (3,5,3'-triiodothyronine) and of T3 into T2 (3,3'-diiodothyronine). Plays a role in providing a source of plasma T3 by deiodination of T4 in peripheral tissues such as liver and kidney.
Gene Name:
DIO1
Uniprot ID:
P49895
Molecular weight:
28924.21
Reactions
Liothyronine + I(-) + A + Hydrogen Ion → Thyroxine + AH(2)details
General function:
Involved in thyroxine 5'-deiodinase activity
Specific function:
Responsible for the deiodination of T4 (3,5,3',5'-tetraiodothyronine) into T3 (3,5,3'-triiodothyronine). Essential for providing the brain with appropriate levels of T3 during the critical period of development.
Gene Name:
DIO2
Uniprot ID:
Q92813
Molecular weight:
30551.48
Reactions
Liothyronine + I(-) + A + Hydrogen Ion → Thyroxine + AH(2)details
General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the oxidative NADPH-dependent deiodination of monoiodotyrosine (L-MIT) or diiodotyrosine (L-DIT). Acts during the hydrolysis of thyroglobulin to liberate iodide, which can then reenter the hormone-producing pathways. Acts more efficiently on monoiodotyrosine than on diiodotyrosine.
Gene Name:
IYD
Uniprot ID:
Q6PHW0
Molecular weight:
33781.22
Reactions
L-Tyrosine + NADP + I(-) → 3,5-Diiodo-L-tyrosine + NADPHdetails
General function:
Involved in thyroxine 5'-deiodinase activity
Specific function:
Responsible for the deiodination of T4 (3,5,3',5'-tetraiodothyronine) into RT3 (3,3',5'-triiodothyronine) and of T3 (3,5,3'-triiodothyronine) into T2 (3,3'-diiodothyronine). RT3 and T2 are inactive metabolites. May play a role in preventing premature exposure of developing fetal tissues to adult levels of thyroid hormones. Can regulate circulating fetal thyroid hormone concentrations throughout gestation. Essential role for regulation of thyroid hormone inactivation during embryological development.
