• Biological Activity: Pertuzumab (anti-HER2) significantly inhibits the HRG-α-stimulated cellular growth of the 11_18 cells. Pertuzumab blocks HRG-α-stimulated phosphorylation of HER3, mitogen-activated protein kinase (MAPK), and Akt. In contrast, pertuzumab fails to block epidermal growth factor (EGF)-stimulated phosphorylation of EGF receptor (EGFR) and MAPK.Immunoprecipitation shows that pertuzumab inhibited HRG-α-stimulated HER2/HER3 heterodimer formation. HRG-α-stimulated HER3 phosphorylation is also observed in the PC-9 cells co-overexpressing EGFR, HER2, and HER3, but the cell growth is neither stimulated by HRG-α nor inhibited by pertuzumab. Pertuzumab binds to ErbB2 near the center of domain II, sterically blocking a binding pocket necessary for receptor dimerization and signaling. Pertuzumab is specific for human ErbB2 and does not bind to rodent ErbB2 (neu) with detectable affinity.
