Proliferation of BCR-FGFR1 fusion proteins is blocked by treatment with the PI3K inhibitor LY294002, suggesting the activation of this pathway downstream of BCR-FGFR1 phosphorylation. Y177 has been shown to be a binding site for GRB2 and to be required for the both the phosphorylation of GAB2 and the development of CML-like disease (Roumiantsev, 2004, Demiroglu, 2001). By analogy with studies in BCR-ABL, where mutation of Y177 abrogates recruitment of PI3K activity to the fusion protein (Sattler, 2002), this suggests that Y177 may serve as a docking site for a complex of GRB2:GAB1:PI3K in the context of BCR-FGFR1 as well.
