Transforming Growth Factor beta (TGF beta) is a biological protein. It is one of a family of proteins known as the TGF-beta superfamily which includes inhibins, activin, anti-müllerian hormone, bone morphogenetic protein, decapentaplegic and Vg-1. TGF beta controls proliferation, differentiation, and other functions in most cell types. It can also act as a negative autocrine growth factor.
