  • Synonyms

    erbB-2, EC 2.7.10.1, p185erbB2, C-erbB-2.

  • Physical Appearance

    Filtered White lyophilized (freeze-dried) powder.

  • Stability

    Store lyophilized ErbB2 at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C.

  • Solubility

    It is recommended to add deionized water to prepare a working stock solution of approximately 0.5mg/ml and let the lyophilized pellet dissolve completely. Product is not sterile! Please filter the product by an appropriate sterile filter before using it on cell culture.

  • Background

    HER2 / ErbB2 (human epidermal growth factor receptor 2) is a member of the ErbB family of receptor tyrosine kinases. It plays a role in cell signalling related to growth, differentiation and proliferation.

    erbB-2 encodes a 185-kDa orphan receptor tyrosine kinase that is constitutively active as a dimer and displays potent oncogenic activity when overexpressed.

    ErbB2 works as a receptor that, upon ligand binding activates downstream signalling pathways such as the MAPK and PI3K/AKT pathways, promoting cell proliferation and survival.

    The activation of ErbB2 leads to enhanced cell growth and survival, making it critical in normal cellular functions and in the pathogenesis of cancer.

    Herstatin, as the product of alternative HER-2 transcript, retains intron 8.
    The herstatin mRNA is expressed in normal human fetal kidney and liver, but is at reduced levels relative to p185HER-2 mRNA in carcinoma cells that contain an amplified HER-2 gene. Herstatin appears to be an inhibitor of p185HER-2, because it disrupts dimers, reduces tyrosine phosphorylation of p185, and inhibits the anchorage-independent growth of transformed cells that overexpress HER-2.
