Recombinant Human ERBB2 Protein, N-His&N-GST-tagged
Product Description
Cat
IMP-4545
Official Symbol
ERBB2
Product Overview
Recombinant cytoplasmic domain (Lys 676-Val 1255) of human ErbB2 (NP_004439.2) was fused with the N-terminal polyhistidine-tagged GST tag at the N-terminus.
Description
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.
