Binding of the ligand triggers homo- and/or heterodimerization of the receptor triggering its autophosphorylation. Heterodimer with
ERBB2 (PubMed:10805725). Interacts with
ERRFI1; inhibits dimerization of the kinase domain and autophosphorylation (PubMed:18046415). Part of a complex with
ERBB2 and either
PIK3C2A or
PIK3C2B (PubMed:10805725). Interacts with
GRB2; an adapter protein coupling the receptor to downstream signaling pathways. Interacts with
GAB2; involved in signaling downstream of
EGFR. Interacts with
STAT3; mediates
EGFR downstream signaling in cell proliferation. Interacts with
RIPK1; involved in NF-kappa-B activation. Interacts (autophosphorylated) with
CBL,
CBLB and
CBLC; involved in
EGFR ubiquitination and regulation. Interacts with
SOCS5; regulates
EGFR degradation through
ELOC- and
ELOB-mediated ubiquitination and proteasomal degradation. Interacts with
PRMT5; methylates
EGFR and enhances interaction with
PTPN6. Interacts (phosphorylated) with
PTPN6; inhibits
EGFR-dependent activation of MAPK/ERK. Interacts with
COPG1; essential for regulation of
EGF-dependent nuclear transport of
EGFR by retrograde trafficking from the Golgi to the ER. Interacts with
TNK2; this interaction is dependent on
EGF stimulation and kinase activity of
EGFR. Interacts with
PCNA; positively regulates
PCNA (PubMed:17115032). Interacts with
PELP1. Interacts with
MUC1. Interacts with
AP2M1. Interacts with
FER. May interact with
EPS8; mediates
EPS8 phosphorylation. Interacts (via SH2 domains) with
GRB2,
NCK1 and
NCK2 (PubMed:10026169). Interacts with ATX2. Interacts with
GAREM1. Interacts (ubiquitinated) with
ANKRD13A/B/D; the interaction is direct and may regulate
EGFR internalization after
EGF stimulation. Interacts with
GPER1; the interaction occurs in an estrogen-dependent manner. Interacts (via C-terminal cytoplasmic kinase domain) with
ZPR1 (via zinc fingers). Interacts with
RNF115 and
RNF126 (PubMed:23418353). Interacts with
GPRC5A (via its transmembrane domain) (PubMed:25311788). Interacts with
FAM83B; positively regulates
EGFR inducing its autophosphorylation in absence of stimulation by
EGF (PubMed:23912460). Interacts with
LAPTM4B; positively correlates with
EGFR activation (PubMed:28479384). Interacts with
STX19 (PubMed:16420529). Interacts with
CD44 (PubMed:23589287).
