Transforming Growth Factor beta: A factor synthesized in a wide variety of tissues. It acts synergistically with Tgf-alpha in inducing phenotypic transformation and can also act as a negative autocrine growth factor. Tgf-beta has a potential role in embryonal development, cellular differentiation, hormone secretion, and immune function. Tgf-beta is found mostly as homodimer forms of separate gene products Tgf-beta1, Tgf-beta2 or Tgf-beta3. Heterodimers composed of Tgf-beta1 and 2 (Tgf-beta1.2) or of Tgf-beta2 and 3 (Tgf-beta2.3) have been isolated. The Tgf-beta proteins are synthesized as precursor proteins.
