The EGF-CFC Protein One-Eyed Pinhead Is Essential for Nodal Signaling
Open accessAbstract
The zebrafish EGF-CFC gene one-eyed pinhead (oep) is required zygotically for the formation of the ventral neuroectoderm, endoderm, and prechordal plate. Here we report that embryos lacking both maternal and zygotic Oep activity are defective in germ layer formation, organizer development, and the positioning of the anterior-posterior axis. An identical phenotype is displayed by double mutants for the nodal-related genes squint and cyclops. Mutations in oep eliminate the response to Squint and Cyclops overexpression but are suppressed by expression of Activin and activated forms of the type I receptor ActRIB and Smad2. Expression of the murine EGF-CFC gene cripto rescues oep mutants. These results suggest a conserved role for EGF-CFC proteins as essential extracellular cofactors for Nodal signaling during vertebrate development.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
