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.
Receptor tyrosine kinases like EGFR transmit signals from the surface of the cell to within the cell. In normal cells, the binding of epidermal growth factor to its receptor on the cell surface is an important signal that promotes cell proliferation.eceptors recognize and bind to other substances, and the binding typically has a specific effect on the cells. EGFR is one of a group of receptors called receptor tyrosine kinases that help regulate cell growth, division, survival, and death.
