Abstract excerpt
Mesendoderm formation and left-right patterning during vertebrate development depend upon selected members of the transforming growth factor beta superfamily, particularly Nodal and Nodal-related ligands. Two type I serine/threonine kinase receptors have been identified for Nodal, ALK4 and ALK7. Mouse embryos lacking ALK4 fail to produce mesendoderm and die shortly after gastrulation, resembling the phenotype of...
