General annotation (Comments)

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). Ref.1

Catalytic activity

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

Subcellular location

Endoplasmic reticulum membrane; Single-pass membrane protein By similarity.

Sequence similarities

Belongs to the iodothyronine deiodinase family.
