Protein

Type II iodothyronine deiodinase

Gene

Dio2

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Catalyzes 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.

Catalytic activityi

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

Post-translational modificationi

Ubiquitinated by MARCH6, leading to its degradation by the proteasome. Deubiquitinated by USP20 and USP33 (By similarity).By similarity

Expressioni

Tissue specificityi

Expressed in cerebral cortex, cerebellum, pituitary gland, mostly in anterior pituitary gland, and pineal gland, as well as in brown adipose tissue (BAT).3 Publications

Inductioni

In the pineal gland, exhibits night/day variations with a 9-fold increased expression at night. Up-regulation is due to a large degree to the release of norepinephrine from nerve terminals in the pineal gland and cAMP signaling pathway. In BAT, up-regulated in animals exposed to cold.3 Publications
