During vertebrate embryogenesis, a left-right axis is established.
Secreted growth factors of the TGF-beta family, including gene products derived from nodal, lefty-1 and lefty-2, play crucial roles in establishing left-right asymmetries.
TGF-beta (Transforming growth factor-beta) is a pleiotropic cytokine that regulates growth and differentiation of diverse types of cells.
TGF-beta actions are directed by ligand-induced activation of TGF-beta receptors.
Complexes formed move into the nucleus, where they act as components of a transcriptional complex.
Lefty, a novel member of the TGF-beta superfamily, inhibits TGF-beta signaling.
Lefty acts to inhibit phosphorylation of Smad2 following activation of the TGF-beta receptor.
Lefty also inhibits events downstream from R-Smad phosphorylation.
Lefty provides a repressed state of TGF-beta-responsive genes.
The Lefty family is comprised of Lefty 1 and Lefty 2 in mouse, and Lefty A and Lefty B in humans.
Members of the TGF-beta superfamily require processing for their activation.
Cleavage is therefore an essential step for Lefty activation.
Lefty is synthesized as a large inactive precursor (42kD) that must be endoproteolytically processed to release the bioactive polypeptide (28kD and 34kD forms).
The 28kD form induces MAPK activity.
