摘要 |
The invention relates to a crystal complex formed by the extracellular domain of EGF receptor (EGFR) and the Fab fragment of anti-EGFR antibody matuzumab (EMD 72000). Especially the invention relates to the identification of the epitope regions on said EGFR, which the antibody matuzumab recognizes as antigen an to which it specifically binds. The invention relates furthermore to protein, peptide and antibody structures which mimic the binding of matuzumab to its epitope region on EGFR, and may be used therefore, as EGFR antagonists with similar or improved properties as compared to matuzumab.
