Target Details

  • Target: ErbB3 (Her3)
  • Molecular weight: 105 kDa
  • Target background: The EGFR family of type I growth factor receptor tyrosine kinases includes EGFR (HER1), c-erbB2 (HER2; neu), c-erbB3 (HER3) and c-erbB4 (HER4). c-erbB3 is normally found in non-dividing differentiated epithelial cells, neurones and hepatocytes. ErbB3 was found to be kinase impaired, having only 1/1000 the autophosphorylation activity of EGFR and no ability to phosphorylate other proteins. Therefore, ErbB3 must act as an allosteric activator. The kinase-impaired ErbB3 is known to form active heterodimers with other members of the ErbB family, most notably the ligand binding-impaired ErbB2. It has approximately 80% prevalence in a wide variety of tumours of the gastro-intestinal tract, and approximately 20% prevalence in breast cancer. This antibody is specific against c-erbB-3 oncoprotein that is expressed in a variety of human normal, foetal and neoplastic epithelial tissues.
