Protein

Type II iodothyronine deiodinase

Gene

DIO2

Organism
Bos taurus (Bovine)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

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 (By similarity).By similarity

Catalytic activityi

3,5,3'-triiodo-L-thyronine + iodide + A + H+ = L-thyroxine + AH2.PROSITE-ProRule annotation
