Identification
BMDB Protein ID BMDBP00548
Secondary Accession Numbers None
Name Thyroxine 5-deiodinase
Synonyms Not Available
Gene Name DIO3
Protein Type Enzyme
Biological Properties
General Function Involved in selenium binding
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.
