Insights into ErbB signaling from the structure of the ErbB2-pertuzumab complex
Contents |
Overview
We have determined the 3.2 A X-ray crystal structure of the extracellular, domain of the human epidermal growth factor receptor 2 (ErbB2 or HER2) in, a complex with the antigen binding fragment of pertuzumab, an anti-ErbB2, monoclonal antibody also known as 2C4 or Omnitarg. Pertuzumab binds to, ErbB2 near the center of domain II, sterically blocking a binding pocket, necessary for receptor dimerization and signaling. The ErbB2-pertuzumab, structure, combined with earlier mutagenesis data, defines the pertuzumab, residues essential for ErbB2 interaction. To analyze the ErbB2 side of the, interface, we have mutated a number of residues contacting pertuzumab and, examined the effects of these mutations on pertuzumab binding and, ErbB2-ErbB3 heterodimerization. We have also shown that conserved residues, previously shown to be necessary for EGF receptor homodimerization may be, dispensible for ErbB2-ErbB3 heterodimerization.
