Target Details for LEFTY2

Target: LEFTY2 (Left-Right Determination Factor 2 (LEFTY2))

Alternative Name: LEFTY2

Background: Background: 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 (42 Kda) that must be endoproteolytically processed to release the bioactive polypeptide (28 kDa and 34 kDa forms). The 28 kDa form induces MAPK activity.
