| Background | Lefty proteins are members of the TGF-β family of cell signaling molecules that are involved in growth and development (1,2). Named for their role in left-right axis determination and their exclusive expression on the left side of the developing mouse embryo, lefty1 and lefty2 contain a cysteine-knot motif that is characteristic of TGF-β related proteins, but lack an alpha-helix and a cysteine residue critical for ligand dimerization (3). Early in vertebrate embryogenesis, lefty represses TGF-β signaling by inhibiting the phosphorylation of Smad2 following activation of the TGF-β receptor (4). Down-regulated very early upon differentiation (5), lefty proteins act as extracellular antagonists of the signaling pathway for Nodal, a TGF-β ligand critical for left-right patterning and formation of the mesoderm and endoderm (6). Similar to other members of the TGF-β superfamily, lefty proproteins undergo cleavage to release a bioactive protein (7). The biologically active 42 kDa lefty precursor and the 28 kDa polypeptide have been shown to induce MAPK activity (7). |
