EGF is a potent growth factor that stimulates the proliferation of various epidermal and epithelial cells. Additionally, EGF has been shown to inhibit gastric secretion, and to be involved in wound healing. EGF signals through a receptor known as c-erbB, which is a class I tyrosine kinase receptor. This receptor also binds with TGF- and VGF (vaccinia virus growth factor). Recombinant rat EGF is a 6.2kD globular protein containing 54 amino acid residues including 3 intramolecular disulfide-bonds.
