In order to resolve questions concerning the in situ structure of the thyrotropin (TSH) receptor, [35S]methionine-labeled thyroid cell preparations were detergent solubilized and proteins exhibiting TSH-dependent binding to TSH-Sepharose were identified. Two such proteins, 43 and 70 kd, are identified in this report as gamma-actin and a member of the heat shock 70 protein family, respectively, based on the microsequence of two peptides from each. Identification of the former was confirmed by Western blotting and immunostaining using anti-actin, the latter by its ability to bind [32P]ATP, a characteristic feature of this family of proteins. The results suggest that TSH-cross linking reports defining TSH receptor subunits should be viewed with caution in the absence of comparative sequence data; consideration must, however, be given to the existence of receptor associated proteins.
