Transforming growth factor α (TGF-alpha; TGF-α) is a mitogenic polypeptide member of the epidermal growth factor (EGF) family of cytokines. TGF-α is composed of 50 amino acids, and displays 35-40% homology with EGF which is the prototypic member of the EGF superfamily. Like EGF, TGF-α is also a ligand of epidermal growth factor receptor (EGFR). TGF-α binds to the EGFR to stimulate an intact RAS/RAF/MAPK pathway, leading to the transcription of genes associated with cell proliferation, invasion and metastasis.
