abstract：:A soluble form of the amino-terminal extracellular (ecto-) domain of the human TSH receptor was generated. This protein was capable of binding TSH and autoimmune antibodies found in Graves' patients. A deletion mutant of the ectodomain lacking nine amino acids in the C-terminal region lost its ability to interact with...
