[Nature of the intracellular thyroid hormone receptor]
Abstract:
Thyroxine-binding proteins were isolated and purified by means of affine chromatography from the blood serum, 105 000 g of cytosol supernatant, non-histone protein fractions of chromatin, extracted with 0.4 M KCl. Identity of their molecular weights and of end aminoacids was found. A comparative study of proteins above, using chromatoelectrophoresis, has shown identity of their primary structure. The data obtained indicate, that chromatin and cytosol contain universal, thyroxine-binding protein, which structure is identical with that of prealbumin thyroxine-binding protein. This protein is considered to be a receptor, realizing the control of genome expression by thyroid hormones.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
