  • Function
    Adapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway.
    Isoform GRB3-3 does not bind to phosphorylated epidermal growth factor receptor (EGFR) but inhibits EGF-induced transactivation of a RAS-responsive element. Isoform GRB3-3 acts as a dominant negative protein over GRB2 and by suppressing proliferative signals, may trigger active programmed cell death.
  • Sequence similarities
    Belongs to the GRB2/sem-5/DRK family.
    Contains 1 SH2 domain.
    Contains 2 SH3 domains.
  • Domain
    The SH3 domains mediate interaction with RALGPS1 and SHB.
  • Cellular localization
    Golgi apparatus.
