SOS1 is presumed to be recruited to FLT3 receptors through interaction with GRB2, as is the case for the wild-type receptor (reviewed in Kazi and Ronnstrand, 2019). SOS is a nucleotide exchange factor for RAS and activates signaling through the RAS-RAF-MAPK pathway downstream of oncogenic FLT3 mutants (Zhang et al, 1999; Mizuki et al, 2000; Hayakawa et al, 2000; Voisset et al, 2010; Arora et al, 2011; reviewed in Kazi and Ronnstrand, 2019).
