DIO1 (Type 1 Deiodinase) is an enzyme that controls thyroid hormone activity by converting thyroxine (T4) — the inactive form — into triiodothyronine (T3), the active form. Primarily located in the liver, kidney, and thyroid gland, DIO1 plays a crucial role in maintaining optimal thyroid hormone levels and supporting tissue-specific metabolic responses.
