DIO2, also known as Type 2 Deiodinase, is a vital enzyme involved in the regulation of thyroid hormone activity. Positioned predominantly within various tissues, including the thyroid gland, brain, and brown adipose tissue, DIO2 plays a pivotal role in controlling thyroid hormone levels and mediating tissue-specific responses to thyroid hormones. One of the primary functions of DIO2 is its involvement in the conversion of thyroxine (T4), the inactive form of thyroid hormone, into triiodothyronine (T3), the active form. DIO2 accomplishes this by catalyzing the removal of an iodine atom from the outer ring of T4, generating T3, which binds to thyroid...
