Fig19-Schematic diagram showing processing of a TGF-B family ligand
FIGURE 19. Schematic diagram showing processing of a TGF-b family ligand.
TGF-b family ligands are translated as dimeric precursor proteins comprising two polypeptide chains, each containing a large N-terminal pro-region and a much smaller C-terminal mature domain. Processing involves cleavage at sites between the two domains and dissociation of the pro-region domain. A homodimeric precursor is shown, as is the case for AMH, but heterodimeric precursors also exist for other TGF-b family members.
