      Background InformationThe ErbB-2 proto-oncogene, also called Neu, EGFR-2 or HER-2, is a member of the transmembrane receptor tyrosine kinase family, which also includes EGF receptor and EGFR-3 (HER-3 or ErbB-3). Although, ErbB-2 does not have any known high-affinity ligands, its kinase activity can be activated without ligand by either overexpression or heteroassociation with other members of the ErbB family. Amplification of the ErbB-2 gene and overexpression of its product has been detected in almost 40% of primary human breast tumors, which correlates with poor prognosis in node positive breast cancer. ErbB-2 overexpression is also observed in ovarian, gastric, salivary and non-small cell lung carcinomas. Because of this, ErbB-2 is one of the major drug targets for breast cancer and other cancer treatments.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. This protein has no ligand binding domain of its own and therefore cannot bind growth factors. 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 signalling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. Allelic variations at amino acid positions 654 and 655 of isoform a (positions 624 and 625 of isoform b) have been reported, with the most common allele, Ile654/Ile655, shown here. Amplification and/or overexpression of this gene has been reported in numerous cancers, including breast and ovarian tumors. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized.
