Background

The growth factor bound protein 2 (GRB2) is a 25 kDa cytosolic protein that contains one src homology (SH2) domain and two SH3 domains (1). GRB2 associates with Tyrosine phosphorylated EGFRs and PDGFRs via its SH2 domain. GRB2 also plays a crucial role in two separate insulin pathways leading from the insulin receptor to the Ras protein thus affecting mitogenic signaling (2). Additionally GBR2, a bifunctional adaptor protein, recruits Sos for Ras activation and subsequent signal transmission (3).
