[GRB2 forms a complex with activated EGFR and the RAS-specific guanine nucleotide exchange factor SOS1, thereby mediating the growth factor-induced activation of RAS. It also acts to link PDGFRB to the Rac signaling pathway. Due to its ability to cause complex formation between proteins involved in growth signaling pathways, GRB2 has been referred to as an adaptor protein. (from LocusLink and OMIM) ( NCI )]
