[ | [https://www.uniprot.org/uniprot/GRB2_HUMAN GRB2_HUMAN] Adapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway.<ref>PMID:1322798</ref> <ref>PMID:8178156</ref> <ref>PMID:19815557</ref> Isoform 2 does not bind to phosphorylated epidermal growth factor receptor (EGFR) but inhibits EGF-induced transactivation of a RAS-responsive element. Isoform 2 acts as a dominant negative protein over GRB2 and by suppressing proliferative signals, may trigger active programmed cell death.<ref>PMID:1322798</ref> <ref>PMID:8178156</ref> <ref>PMID:19815557</ref> | ||
