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 rat ErbB2 (AAH61863.1) extracellular domain (Met 4-Thr 656) was fused with the Fc region of human IgG1 at the C-terminus. |
Source | HEK293 |
Predicted N Terminal | Thr 26 |
AA Sequence | Met 4-Thr 656 |
Molecular Weight | The recombinant rat ErbB2/Fc is a disulfide-linked homodimer. The reduced monomer comprises 872 amino acids and predicts a molecular mass of 97 kDa. The apparent molecular mass of the rat ErbB2/Fc monomer is approximately 130 kDa in SDS-PAGE under reducing conditions due to glycosylation. |
Purity | >85% as determined by SDS-PAGE |
Endotoxin | < 1.0 EU per μg of the protein as determined by the LAL method |
Bioactivity | Please contact us for detailed information |
