CD340, also commonly known as HER2 or ErbB2, is a member of the epidermal growth factor receptor family of cell membrane tyrosine kinases containing a single transmembrane domain. CD340 contains three furin repeats and two cheY homologous receiver domains in the extracellular region. Although CD340 itself contains no ligand binding domain, it interacts with other EGF receptor family members to form a heterodimer, stabilize ligand binding, and enhance kinase-mediated downstream signaling. CD340 has been shown to be involved in embryonic development and cancer progression; this protein is amplified in adenocarcinoma of the lung, some breast cancers, glioblastoma, gastric cancer, and ovarian carcinoma, where it functions as an oncogene. Overexpression of CD340 in breast cancers has been shown to confer Taxol resistance, and CD340 is a therapeutic target in a number of human cancers. CD340 activation is accompanied by autophosphorylation at multiple tyrosine residues including Tyr1248.
