EGFR phosphorylates intracellular domain of NOTCH3 (NICD3) on an unknown tyrosine residue. EGFR signaling inhibits NICD3-mediated transcription. It is not known whether EGFR-mediated phosphorylation of NICD3 affects NICD3 nuclear translocation or the formation of the NOTCH3 coactivator complex. Erlotinib treatment, which inhibits EGFR activation, results in increased NOTCH3 signaling and induction of stem-like phenotype in treated cells (Arasada et al. 2014).
