PDGFRA Y288C and PDGFRA del375-455 signal through the RAS-MAPK kinase cascade, as assessed by the presence of phosphorylated MAPK3 and MAPK1 (ERK1 and ERK2, respectively) by Western blot analysis. Although it has not been examined in detail, it is likely this occurs through the recruitment of GRB:SOS as is the case for the wild-type receptor (Ozawa et al, 2010; Ip et al, 2018).
