Phosphorylated tyrosine residue Y1356 of MET receptor creates a docking site for the SH2 domain of GRB2 splicing isoform 1 (GRB2-1) (Ponzetto et al. 1994, Weidner et al. 1995). Asparagine residue N1358 of MET is important for GRB2-1 binding (Fournier et al. 1996). GRB2-1 and SOS1, which form a complex, are both important for RAS activation downstream of MET (Shen and Novak 1997, Besser et al. 1997).

MUC20 negatively regulates binding of GRB2-1 to MET (Higuchi et al. 2004).
