NPM-ALK, TFG-ALK and ATIC-ALK fusion proteins have been demonstrated to bind GRB2 by GST-pulldown and co-immunoprecipitation (Fujimoto et al, 1996; Trinei et al, 2000; Hernandez et al, 2002). In the case of NPM-ALK, GRB binding is independent of the recruitment of SHC and IRS1, as the GRB2 interaction is not abrogated by the mutation of the primary SHC and IRS binding site at Y567 (Fujimoto et al, 1996). Neither direct binding of GRB2 nor a defined GRB2 binding site have been identified in the context of an ALK fusion protein, and recruitment may be mediated by other adaptor proteins, including PTPN11 (Voena et al, 2007). GRB2 binding appears to contribute to the transformation potential of the ALK fusion proteins, possibly by linking to the MAP kinase signaling pathway (Fujimoto et al, 1996; reviewed in Palmer, 2009). In some ALK fusions, the fusion partner may also be responsible for activation of the MAP kinase signaling pathway, as is the case for EML4-ALK fusions (Hrustanovic et al 2015).
