Part Descriptions

LP15900-1   Thyroxine
The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosine (monoiodotyrosine) and the coupling of iodotyrosine (diiodotyrosine) in thyroglobulin. Thyroxine is separated from thyroglobulin by proteolysis and released in the blood. Thyroxine is peripherally deiodinated to form triiodothyronine which exerts broad stimulatory effects on cell metabolism. Source: National Library of Medicine, MeSH 2006

LP32168-4   Thyroxine binding globulin
Thyroxine-binding globulin (TBG) is one of three proteins (along with transthyretin and albumin) responsible for carrying the thyroid hormones thyroxine (T4) and 3,5,3€™-triiodothyronine (T3) in the bloodstream. Of these three proteins, TBG has the highest affinity for T4 and T3, but is present in the lowest concentration. Despite its low concentration, TBG carries the majority of T4 in serum. Due to the very low serum concentration of T4 T3, TBG is rarely more than 25% saturated with its ligand. Unlike transthyretin and albumin, TBG has a single binding site for T4T3. Genomically, TBG is a serpin, although it has no inhibitory function like many other members of this class of proteins. TBG is synthesized primarily in the liver as a 54 kDa protein.
