Background Information

Her2, or ErbB2, is a member of the EGF receptor family of receptor tyrosine kinases. It has no ligand-binding domain of its own. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signaling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase.
