CC -!- FUNCTION: Responsible for the deiodination of T4 (3,5,3',5'-
CC tetraiodothyronine) into T3 (3,5,3'-triiodothyronine). Essential for
CC providing the brain with appropriate levels of T3 during the critical
CC period of development.
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 IsoId=Q92813-3; Sequence=VSP_060028, VSP_060029, VSP_060030;
CC -!- TISSUE SPECIFICITY: Isoform 1 is expressed in the lung, trachea,
CC kidney, heart, skeletal muscle, placenta, fetal brain and several
CC regions of the adult brain (PubMed:8755651, PubMed:11165050). Isoform 2
CC is expressed in the brain, heart, kidney and trachea (PubMed:11165050).
CC {ECO:0000269|PubMed:11165050, ECO:0000269|PubMed:8755651}.
CC -!- PTM: Ubiquitinated by MARCHF6, leading to its degradation by the
CC proteasome. Deubiquitinated by USP20 and USP33.
CC {ECO:0000269|PubMed:12865408, ECO:0000269|PubMed:19651899}.
CC -!- MISCELLANEOUS: [Isoform 2]: Has a Sec in positions 90, 169 and 302.
CC {ECO:0000305}.
CC -!- MISCELLANEOUS: [Isoform 3]: Has a Sec in position 37. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the iodothyronine deiodinase family.
CC {ECO:0000305}.
