CC -!- FUNCTION: Responsible for the deiodination of T4 (3,5,3',5'-
CC tetraiodothyronine) into T3 (3,5,3'-triiodothyronine) and of T3 into T2
CC (3,3'-diiodothyronine). Plays a role in providing a source of plasma T3
CC by deiodination of T4 in peripheral tissues such as liver and kidney.
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3,3',5-triiodo-L-thyronine + A + H(+) + iodide = AH2 + L-
CC thyroxine; Xref=Rhea:RHEA:19745, ChEBI:CHEBI:13193,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16382, ChEBI:CHEBI:17499,
CC ChEBI:CHEBI:58448, ChEBI:CHEBI:533015; EC=1.21.99.4;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU10107};
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC Single-pass membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the iodothyronine deiodinase family.
CC {ECO:0000305}.
