Epidermal Growth Factor Receptor Signaling Pathway Core Components -
The Epidermal Growth Factor Receptor (EGFR) signaling pathway is used multiple times during development (FBrf0190321). It is activated by the binding of a secreted ligand to the receptor tyrosine kinase Egfr and acts via the canonical Ras/Raf/MAP kinase (ERK) cascade. (Adapted from FBrf0190321 and FBrf0221727).
EGFR AGONISTS -
Epidermal Growth Factor Receptor (EGFR) agonists are secreted ligands that activate the Egfr receptor tyrosine kinase.
