We constructed a series of TSH-LH/CG receptor chimeras by homologous substitution of relatively small regions of the TSH receptor extracellular domain for the corresponding region of the extracellular domain of the LH/CG receptor. Constructs were stably expressed in Chinese hamster ovary cells. Of the five chimeric receptors, only TSH-LHR-14, which contains mid-region domain C (amino acid residues 171–260) of the extracellular component of the TSH receptor, exhibited TSH binding of relatively high affinity. Consistent with this TSH binding, chimera TSH-LHR-14 was the only one that demonstrated a functional response to TSH stimulation in terms of intracellular cAMP generation. These data indicate that domain C plays a vital role in TSH receptor function.
