The thyroid hormones function via a well-studied set of nuclear receptors, termed the thyroid hormone receptors. These receptors, together with corepressor molecules, bind DNA regions called thyroid hormone response elements (TREs) near genes. This receptor-corepressor-DNA complex can block gene transcription. Triiodothyronine (T3), which is the active form of thyroxine (T4), goes on to bind to receptors. The deiodinase catalyzed reaction removes an iodine atom fr… WebApr 21, 2024 · The thyroid gland releases important hormones, thyroxine (T4), 3, 5, 3′-triiodothyronine (T3), and 3, 5, 3′-triiodothyronine (rT3). The thyroid gland secretes 100 nmol of T4 and 5 nmol of T3 daily. Thyroxine is therefore the main hormone that is metabolized and degraded through a deiodination process which converts it to T3.
