moreover , in comparisons of receptors with similar overall autophosphorylation but very different activations ( or similar activations but different extents of autophosphorylation ) , achieved by omitting insulin or varying [ atp ] , the phosphorylation of peptide 1144-1152 tracks closely with kinase activation , and phosphorylation of sites and mr 4000-5000 tryptic peptide ( presumably tyr 953 and/or 960 ) tract nearly as well .
