Recombinant Rat HER2 / ErbB2 Protein (His tag)
Human epidermal growth factor receptor 2 (HER2), also known as ErbB2, NEU, and CD340, is a type I membrane glycoprotein, and belongs to the epidermal growth factor (EGF) receptor family. HER2 protein cannot bind growth factors due to the lacking of ligand binding domain of its own and autoinhibited constitutively. However, HER2 forms a heterodimer with other ligand-bound EGF receptor family members, therefore stabilizes ligand binding and enhances kinase-mediated activation of downstream molecules. HER2 plays a key role in development, cell proliferation and differentiation. HER2 gene has been reported to associate with malignancy and a poor prognosis in numerous carcinomas, including breast, prostate, ovarian, lung cancers and so on.
Synonym(s) : ErbB2 , Neu , p185erbB2
Species(s) : Rat
Protein Expression Host : Human Cells
Protein Construction : A DNA sequence encoding the rat ErbB2 (AAH61863.1) extracellular domain (Met 4-Thr 656) was expressed, fused with a polyhistidine tag at the C-terminus.
Predicted N-terminal amino acid : Thr 26
Molecular weight/mass : The recombinant rat ErbB2 comprises 642 amino acids and predicts a molecular mass of 71.3 kDa. The apparent molecular mass of the rat ErbB2 is approximately 110 kDa in SDS-PAGE under reducing conditions due to glycosylation.
