abstract：:Some TSH receptors (TSHR) on the cell surface cleave into A and B subunits. Cleavage at upstream Site 1 is followed by the proteolytic excision of an intervening C peptide region terminating at a downstream Site 2. Although present evidence suggests that Site 1 lies between amino acid residues 303 and 317, the mechani...
