Importance of the spacing of Glu residues. (A) A series of clones, based on the mutant CONS.C2xE, were constructed varying the spacing between two Glu residues, from a minimum spacing of two residues (diad mutant) to a maximum spacing of eight residues (octad mutant). (B) Transformation by each isolate shown in (A) was quantitated as a percentage of p185neu. Numerical results of transformation assays are presented graphically and represent the average values from two independent experiments, normalized by cotransfection with pSV2neo.
