Abstract : TGF alpha is a small protein which can bind to, and activate, epidermal growth factor receptors (EGF-R) on the surface of epithelial, mesenchymal and a range of cancer cells, causing the initiation of DNA synthesis and subsequent division. Despite intensive efforts using site-directed mutagenesis, synthetic peptide fragments, and determination of the secondary and tertiary folding of TGF alpha in solution, the role and importance of many structural features in mediating EGF-R activation remain ill-defined. We have assayed the ability of EGF-R to bind to peptide fragments of TGF alpha.
