Epidermal Growth Factor Related Transforming Growth Factor
[Transforming growth factors (TGFs) are biologically active polypeptides that reversibly confer the transformed phenotype on cultured cells. Alpha-TGF shows about 40% sequence homology with epidermal growth factor and competes with EGF for binding to the EGF receptor, stimulating its phosphorylation and producing a mitogenic response (OMIM) ( NCI )]
