Background	C-erbB-2 (erythroblastosis oncogene B), also known as HER2 (Human Epidermal Growth Factor Receptor 2), or Neu, CD340 and p185 is a protein that in humans is encoded by the ERBB2 gene. Amplification or overexpression of this gene has been shown to play an important role in the pathogenesis and progression of certain aggressive types of breast cancer, as well as many other epithelial malignancies and brain tumors. In recent years it has become an important biomarker and target of therapy for disease. ERBB2 is a known proto-oncogene located at the long arm of human chromosome 17 (17q21-q22). The oncogene was found to code for EGFR. Gene cloning showed that HER2, Neu and ErbB-2 are all encoded by the same gene. The ErbB family is composed of plasma membrane-bound receptor tyrosine kinases, that contain an extracellular ligand binding domain, a transmembrane domain and an intracellular domain that can interact with a multitude of signaling molecules. HER2 can heterodimerise with any of the other three receptors and is considered to be the preferred dimerisation partner of the other ErbB receptors. Dimerisation results in the autophosphorylation of tyrosine residues within the cytoplasmic domain of the receptors and initiates a variety of signaling pathways.
