Background	Receptor tyrosine-protein kinase erbB-2, also known as CD340 (cluster of differentiation 340), proto-oncogene Neu, Erbb2 (rodent), or ERBB2 (human), is a protein that in humans is encoded by the ERBB2 gene. ERBB is abbreviated from erythroblastic oncogene B, a gene isolated from avian genome. It is also frequently called HER2 (from human epidermal growth factor receptor 2) or HER2/neu. ERBB2, commonly referred to as HER2, is amplified and/or overexpressed in 20-30% of invasive breast carcinomas. HER2-positive breast cancer is treated in a separate manner from other subtypes of breast cancer and commonly presents as more aggressive disease. Metastatic HER2-positive breast cancer is now commonly treated with HER2-targeted therapy. Apart from being amplified/overexpressed, ERBB2 activating mutations have been shown to have clinical importance in HER2-negative breast cancer. These mutations have shown sensitivity to the tyrosine kinase inhibitor neratinib, and highlight the importance of clinical sequencing efforts in treating breast cancer.
Description	A DNA sequence encoding the human ERBB2 (Met1-Thr652) was expressed with five amino acids (DDDDK) at the C-terminus. The purified protein was biotinylated in vitro.
