Antibody Protection Reveals Extended Epitopes on the Human TSH Receptor
Stimulating, and some blocking, antibodies to the TSH receptor (TSHR) have conformation-dependent epitopes reported to involve primarily the leucine rich repeat region of the ectodomain (LRD). However, successful crystallization of TSHR residues 22-260 has omitted important extracellular non-LRD residues including the hinge region which connects the TSHR ectodomain to the transmembrane domain a...
متن کاملFolding-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...
متن کاملAllosteric modulators hit the TSH receptor.
The receptor for TSH (TSHR) has captured our interest and imagination since it was first demonstrated to be a major human antigen in autoimmune thyroid disease. The original realization that the immunoglobulin fraction of sera from patients with Graves’ disease incorporated unique human autoantibodies to the TSHR led to the unraveling of the great complexity that the TSHR exhibits in comparison...
متن کاملEnhanced response to mouse thyroid-stimulating hormone (TSH) receptor immunization in TSH receptor-knockout mice.
Graves-like hyperthyroidism is induced in BALB/c mice by immunization with adenovirus expressing the human TSH receptor (TSHR) A-subunit (amino acids 1-289). However, because of nonidentity between the human and mouse TSHR ( approximately 87% amino acid homology), we compared the responses of mice immunized with adenoviruses expressing either the mouse or the human TSHR A-subunit. Wild-type (wt...
