EGFRvIII: An Oncogene with Ambiguous Role

Figure 1

Schematic structure of EGFRWT (a) and EGFRvIII (b). Both receptors are composed of extracellular (I–IV), transmembrane, and intracellular domains, and the major difference is deletion of exons 2–7 encoding extracellular domains I and II in mutated receptor. As a result of deletion, EGFRvIII is unable to bind known ligands and shows enhanced stability in cell membrane.
