Biochem/physiol Actions

Transforming growth factor-α (TGF-α), is a 5.5 kDa polypeptide containing 50 amino acids in its mature form. It was originally identified as an agent that reversibly confers a transformed phenotype upon normal non-neoplastic cells, such as normal rat kidney fibroblasts. This activity requires the presence of transforming growth factor-β (TGF-β), which potentiates the action of TGF-α via a separate receptor. TGF-α is synthesized by monocytes, keratinocytes and many tissues and tumors. Mice genetically engineered to be lacking TGF-α expression showed no abnormalities except for the detection of a "wavy" hair coat. TGF-α exerts its action through the EGF receptor.
