Human Anti-ERBB3 (clone H3) scFv-Fc Chimera (CAT#: VS-0125-FY22)

The main function of the anti-HER3 scFv-Fc is to target the HER3 antigen and induce apoptosis in tumor cells. By specifically binding to the HER3 antigen, this anti-HER3 scFv-Fc fusion protein can effectively inhibit tumor cell proliferation and promote apoptosis, offering new insights for cancer treatment. Furthermore, its potential applications in inducing tumor apoptosis and enhancing anti-tumor efficacy make this fusion protein a significant direction in contemporary cancer immunotherapy research.

  • Function
  • Tyrosine-protein kinase that plays an essential role as cell surface receptor for neuregulins.
    Binds to neuregulin-1 (NRG1) and is activated by it; ligand-binding increases phosphorylation on tyrosine residues and promotes its association with the p85 subunit of phosphatidylinositol 3-kinase.
    May also be activated by CSPG5.
    Involved in the regulation of myeloid cell differentiation.
