[[http://www.uniprot.org/uniprot/GRB2_MOUSE GRB2_MOUSE]] Adapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway.  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 (By similarity). [[http://www.uniprot.org/uniprot/SOS1_MOUSE SOS1_MOUSE]] Promotes the exchange of Ras-bound GDP by GTP (By similarity).
