Facts about Type I iodothyronine deiodinase.
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 like liver and kidney..
