#XL - T Zoology

Monomeric active forms of all members of the TGF-β family (3 conserved intramolecular disulfide Linkages) contain a conserved cysteine residue that forms a disulfide bond links TGF-β monomers into functional homodimers

and heterodimers

TGF-β is synthesized with a, 

250-residue N-terminal prodomain

∼110-residue C-terminal TGF-β domain
