The Nodal family of proteins, a subset of the transforming growth factor beta (TGFβ) superfamily, is responsible for mesoendoderm induction, patterning of the nervous system, and determination of dorsal- ventral axis in vertebrate embryos. Activation of the Nodal pathway involves nodal binding to activin and activin-like receptors which leads to phosphorylation of the Smad2.
