Description : |
Nodal is a secreted protein that is a member of the Transforming Growth Factorβ (TGFβ) superfamily. Nodal was named for its localized expression in the mouse node during gastrulation, and is first detected in the early primitive streak during mesoderm formation. Expression of the Nodal gene occurs asymmetrically in the left, but not right, lateral plate during somitogenesis. Nodal proteins play crucial roles in mesoderm formation and both anteriorposterior and leftright axis formation during vertebrate development. Members of the Nodal gene family include mouse Nodal, chick cNR1, frog Xnr14, and zebrafish cyclops. Biologically active Nodal is a disulfidelinked homodimer and contains all seven of the cysteine residues necessary for formation of the "cysteine knot" characteristic of TGFβrelated molecules. Mouse Nodal is 34 39% homologous in the conserved region to other TGFβ superfamily members. Nodal has been shown to signal through a mechanism related to the Activin pathway, and signaling is mediated through both Smad2 and 3. |
