Figure 3.
Schematic representation of the most common EGFR mutant alleles observed in cancer and gliomas. The amino acid numbering represented is for the EGFR mature protein without the 24-residue signal peptide. The 12 known intracellular tyrosine phosphorylation sites are indicated. LB, ligand binding domain; CR1/2, cysteine-rich domain. Only those point mutants found at a frequency of >2% in gliomas are indicated and can be found on the COSMIC website (http://www.sanger.ac.uk/genetics/CGP/cosmic/).
