Activation of the MAP kinase signaling pathway downstream of oncogenic KIT mutants, as evidenced by the presence of phosphorylated ERK proteins, likely depends on the SOS-mediated nucleotide exchange of GDP for GTP on RAS, as is the case for the wild-type receptor (Frost et al, 2002; Chi et al, 2010; Garner et al, 2014; Monsel et al, 2010; Obata et al, 2017; reviewed in Abbaspour Babaei et al, 2016; Lennartsson and Roonstrand, 2012).
