Tyrosine residue Y992 (corresponding to Y1016 when counting from the first amino acid of the EGFR precursor, prior to cleavage of the 24-amino acid signal peptide at the N-terminus), a docking site for PLC-gamma 1 (PLCG1), is phosphorylated in EGFR cancer mutants and expected to recruit PLC-gamma 1 in the same way as the wild-type EGFR receptor. Phosphorylation of Y992 (corresponding to Y1016 when counting from the first amino acid of the EGFR precursor, prior to cleavage of the 24-amino acid signal peptide at the N-terminus) has been directly demonstrated for the following EGFR cancer mutants: EGFR L858R mutant (Sordella et al. 2004, Choi et al. 2007); EGFR G719S mutant (Choi et al. 2007); EGFR L747_P753delinsS mutant (Sordella et al. 2004, Choi et ak, 2007); EGFR L861Q mutant (Choi et al. 2007); EGFRvIII mutant (Grandal et al. 2007); EGFR A289V mutant (Lee et al. 2006); EGFR D770_N771insNPG mutant (Xu et al. 2007); EGFR N771_H773dup mutant (Xu et al. 2007); EGFR K739_I744dup mutant (Xu et al. 2007); EGFR A767_V769dup mutant (Xu et al. 2007).
