Preferred Label : ERBB Family Signaling Pathway;
NCIt related terms : ErbB signaling pathway;
Alternative definition : KEGG: The ErbB family of receptor tyrosine kinases (RTKs) couples binding of extracellular
growth factor ligands to intracellular signaling pathways regulating diverse biologic
responses, including proliferation, differentiation, cell motility, and survival.
Ligand binding to the four closely related members of this RTK family-epidermal growth
factor receptor (EGFR, also known as ErbB-1 or HER1), ErbB-2 (HER2), ErbB-3 (HER3),
and ErbB-4 (HER4)-induces the formation of receptor homo- and heterodimers and the
activation of the intrinsic kinase domain, resulting in phosphorylation on specific
tyrosine residues (pY) within the cytoplasmic tail. Signaling effectors containing
binding pockets for pY-containing peptides are recruited to activated receptors and
induce the various signaling pathways. The Shc- and/or Grb2-activated mitogen-activated
protein kinase (MAPK) pathway is a common target downstream of all ErbB receptors.
Similarly, the phosphatidylinositol-3-kinase (PI-3K) pathway is directly or indirectly
activated by most ErbBs. Several cytoplasmic docking proteins appear to be recruited
by specific ErbB receptors and less exploited by others. These include the adaptors
Crk, Nck, the phospholipase C gamma (PLCgamma), the intracellular tyrosine kinase
Src, or the Cbl E3 ubiquitin protein ligase.;
