Folding-dependent binding of thyrotropin (TSH) and TSH receptor autoantibodies to the murine TSH receptor ectodomain.
The mouse TSH receptor ectodomain (mTSHR-ecd) was amplified from murine thyroid complementary DNA and ligated into the pAcGP67B insect cell vector, and the nucleotide sequence was confirmed. Employing a baculovirus-insect cell system, the mTSHR-ecd (amino acids 22-415) was expressed as a fusion protein with the gp67 insect cell signal sequence at the NH2-terminus and a C-terminal six-histidine ...
متن کاملTSH Receptor Mutations and Diseases
On a theoretical basis, for a hormone receptor, “gain of function” may have several meanings: (i) activation in the absence of ligand (constitutivity); (ii) increased sensitivity to its normal agonist; (iii) increased, or de novo sensitivity to an allosteric modulator; (iv) broadening of its specificity. When the receptor is part of a chemostat, as is the case for the TSH receptor, the first si...

Citation: Kahaly GJ and Diana T (2017) TSH Receptor Antibody Functionality and Nomenclature. This general commentary on the above, recently published New England Journal of Medicine review article wishes to clarify both the nomenclature as well as the role of autoantibodies (Ab) to the TSH receptor (TSH-R) pertaining to the serological diagnosis of Graves' disease (GD). Various terms have been ...
متن کاملChapter 16a - TSH RECEPTOR MUTATIONS AND DISEASES
The thyroid-stimulating hormone (TSH) receptor (TSHR) is a member of the glycoprotein hormone receptors (GPHRs), a sub-group of class A G protein-coupled receptors (GPCRs). TSHR and its ligand thyrotropin are of essential importance for growth and function of the thyroid gland. The TSHR activates different G-protein subtypes and signaling pathways, of which Gs and Gq induced signaling are of hi...
متن کاملCharacterization of regulation of thyrotropin (TSH) receptor function in thyroid plasma membrane: interaction between TSH receptor function and activation of adenosine 3',5'-monophosphate-dependent protein kinase.
The changes in the characteristics of thyrotropin (TSH) binding to thyroid plasma membranes during the activation of cyclic AMP-dependent protein kinase in the membranes were studied. Preincubation of thyroid plasma membranes with TSH or cyclic AMP reduced the maximal binding capacity but increased the association rate for TSH binding. In double reciprocal analysis, a marked reduction of the to...
