The 110 kDa catalytic subunit of PI3K is likely recruited to FLT3 fusions through interaction with the p85 regulatory subunit, as is the case for the wild-type receptor. GAB2-mediated conformational changes in the p85 regulatory subunit stimulate interaction with p110, and promote PI3K/AKT signaling downstream of activated FLT3 (Zhang et al, 1999; Zhang et al, 2000; Vu et al, 2007; Masson et al, 2009; Grand et al, 2007; Troadec et al, 2017; Chonabayashi et al, 2013; reviewed in Kazi and Ronnstrand, 2019).
