In the majority of studies, trans-autophosphorylation of specific tyrosine residues of ERBB2 KD mutants and its heterodimerization partners, EGFR and ERBB3 (and ERBB4), has not been examined, and they are assumed to be identical to tyrosine residues that undergo trans-autophosphorylation in the wild type ERBB2 heterodimers. ERBB2 H878Y is also phosphorylated on the substitution tyrosine Y878 (Hu, Wan et al. 2015). EGFR and ERBB3 undergo trans-autophosphorylation in the presence of ERBB2 L755_T759del mutant, while ERBB2 L755_T759del remains unphosphorylated (Bose et al. 2013).
