  • Title: Epidermal growth factor: the receptor and its function.
    Author: Todderud G, Carpenter G.
    Journal: Biofactors; 1989 Mar; 2(1):11-5. PubMed ID: 2553047.
    Abstract:
    Epidermal growth factor (EGF) is a small polypeptide hormone with mitogenic properties in vivo and in vitro. EGF elicits biologic responses by binding to a cell surface receptor which is a transmembrane glycoprotein containing a cytoplasmic protein tyrosine kinase. EGF responses are mediated by ligand binding and activation of this intrinsic protein kinase. The receptor can be phosphorylated by other protein kinases, and this may regulate receptor function. Stimulation of the receptor tyrosine kinase activity by ligand binding must regulate the activity of an as yet undefined molecule(s) responsible for transmitting a mitogenic signal to the nucleus.
