    摘要: Two novel proteins have been designated "cerberus" and "frzb-1," respectively. Cerberus is expressed as a secreted peptide during embryogenesis of the Xenopus embryo, and is expressed specifically in the head organizer region. This new molecule has endodermal, cardiac, and neural tissue inducing activity, that should prove useful in therapeutic, diagnostic, and clinical applications requiring regeneration, differentiation, or repair of these and other tissues. Frzb-1 is a soluble antagonist of growth factors of the Wnt family that acts by binding to Wnt growth factors in the extracellular space. A third novel protein is designated "PAPC" which promotes the formation of dorsal mesoderm and somites in the embryo.

    摘要: A functional polypeptide designated "chordin" is described that is capable of inducing dorsal (and neural tissue) development in vertebrates, and which appears to be a secreted protein. There are substantial regions of conservation with Xenopus chordin with mouse chordin, and the human gene should also be similar in those regions. A full length Xenopus cDNA for chordin is illustrated by FIGS. 1A-1F, and contains a reading frame encoding a 941 residue, 105 kDa precursor protein.
