Activation of downstream RAS signaling was shown for ERBB2 S653C (de Martino et al. 2014) and ERBB2 R678Q (Bose et al. 2013, de Martino et al. 2014) through activating tyrosine phosphorylation on ERKs (MAPK1 and MAPK3). It is assumed that heterodimers of ERBB2 TMD/JMD mutants and EGFR, like the wild type ERBB2:EGFR heterodimers, directly bind to GRB:SOS1 complex.
