SOS-mediated exchange of GTP for GDP on RAS is predicted to be stimulated by gain-of-function PDGFRA mutants, based on the increased levels of phosphorylated MAPK3 and MAPK1 proteins (ERK1 and ERK2, respectively) (Heinrich et al, 2003; Corless et al, 2005; Ohashi et al, 2004; Velghe et al, 2014; reviewed in Corless et al, 2011; Roskoski, 2018).
