EXPERIMENTAL STUDY Thyrotropin regulates tyrosine sulfation of thyroglobulin
Objective: To study the regulation of thyroglobulin sulfation by thyrotropin (TSH) and iodide. Sulfation, a widespread post-translational modification of proteins, is involved in various biological activities. Thyroglobulin has been reported to be sulfated but, to date, the role of sulfate residues in the metabolism and function of thyroglobulin is not known; moreover, the regulation of thyrogl...
متن کاملTyrosine Sulfation of Statherin
Tyrosylprotein sulfotransferase (TPST), responsible for the sulfation of a variety of secretory and membrane proteins, has been identified and characterized in submandibular salivary glands (William et al. Arch Biochem Biophys 1997; 338: 90-96). In the present study we demonstrate the sulfation of a salivary secretory protein, statherin, by the tyrosylprotein sulfotransferase present in human s...
متن کاملThyrotropin controls transcription of the thyroglobulin gene.
The availability of rat thyroglobulin cDNA clones was exploited to study the regulation of thyroglobulin gene transcription by thyrotropin (TSH). Groups of rats were subjected to treatments leading to reduction or increase in the rat serum TSH (rTSH) levels. Thyroid gland nuclei were isolated, incubated in vitro in the presence of 32P-labeled uridine triphosphate, and thyroglobulin transcripts ...
متن کاملHuman fibrocytes coexpress thyroglobulin and thyrotropin receptor.
Thyroglobulin (Tg) is the macromolecular precursor of thyroid hormones and is thought to be uniquely expressed by thyroid epithelial cells. Tg and the thyroid-stimulating hormone receptor (TSHR) are targets for autoantibody generation in the autoimmune disorder Graves disease (GD). Fully expressed GD is characterized by thyroid overactivity and orbital tissue inflammation and remodeling. This p...
متن کاملTyrosine O Sulfation: An Overview
Tyrosine O sulfation is a post translational modification (PTM) originally discovered by Bettelheim in 1954 in the bovine protein fibrinogen. Currently, this PTM is found only in secreted and transmembrane proteins of higher eukaryotes. This article gives an overview of experimental tools to study tyrosine O sulfation and also describes the biological function of this PTM.
