Epidermal Growth Factor (EGF) is known for its role in promoting cell division and cellular differentiation in developing animals, but we know surprising little about what EGF does in vivo in mature adult animals.
The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/c-neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4).Mutations affecting EGFR expression or activity could result in cancer.pidermal growth factor receptor (EGFR) exists on the cell surface and is activated by binding of its specific ligands, including epidermal growth factor and transforming growth factor Î± (TGFÎ±) (note, a full list of the ligands able to activate EGFR and other members of the ErbB family is given in the ErbB article).
