1 Despite these defects of kinase activity, anti-phosphotyrosine immunoblotting of whole cell lysates and anti-phosphotyrosine immunoprecipitation of 32P-labeled cells showed insulin-stimulated tyrosine phosphorylation of a protein of approximately 185 kDa to an extent comparable to that seen in CHO cells expressing wild-type human insulin receptors.
