Epidermal growth factor receptor (EGFR) is a 170kDa transmembrane glycoprotein receptor tyrosine kinase that, when activated by epidermal growth factor (EGF), affects cell growth and differentiation in normal and cancer cells (1). Binding of EGF or TGF alpha to EGFR activates
tyrosine kinase activity of the receptor (2). The carboxy terminal tyrosine residues on EGFR, Tyr 1068, Tyr 1148, and Tyr 1173, are the major sites of autophosphorylation, which occurs as a result of EGF binding (3). EGFR overexpression is exhibited various cancer, such as glioma, colorectal carcinoma, breast carcinoma, and head and neck carcinoma 4). Phosphorylation at Ser 1070 has been implicated in altered receptor desensitization and receptor internalization
modification of EGFR (5).
