MAP kinase signaling is activated downstream of gain-of-function missense and in-frame deletion PDGFRA mutants, as assessed by 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). RAS and MAPK activation is assumed to occur through the recruitment of GRB2:SOS1 to phosphorylated T720, as is the case for the wild-type receptor, although this has not been conclusively demonstrated (Bazenet et al, 1996; reviewed in Corless et al, 2011; Roskoski, 2018).
