FLT3 fusions signal through the PI3K/AKT pathway as assessed by increased phosphorylation of AKT downstream of activated fusions (Grand et al, 2007; Vu et al, 2009; Troadec et al, 20017; Chonabayashi et al, 2013; reviewed in Kazi and Roonstrand, 2019). Recruitment and activation of PI3K is likely mediated by GRB2-GAB2 as is the case for the wild-type receptor, although this has not been directly demonstrated (Zhang et al, 1999; Zhang et al, 2000; Masson et al, 2009).
