the CFC domain, are known to be encoded by two evolutionarily conserved exons, it is generally assumed, based on weak primary sequence identity, that the remaining parts of the protein differ among vertebrates, suggesting that known members of the EGF–CFC family do not represent true orthologs....
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 th...
We report that Vg1 and GDF1 signaling in zebrafish also depends on EGF-CFC proteins, but not on Nodal signals. Correspondingly, we find that in Xenopus Vg1 and GDF1 bind to and signal through Activin receptors only in the presence of EGF-CFC proteins. These results establish that multiple...
The EGF-CFC proteins have been recently recognized as a novel family of extracellular factors required during early vertebrate development. Cripto is the founder member of the EGF-CFC family initially related to the epidermal growth factor (EGF); its expression is increased in human colon, gastric...

EGF主要由表皮细胞产生,并且对于皮肤细胞的生长和修复起着关键作用。 EGF的电荷特性也是其功能的重要方面之一。根据化学性质,EGF是一种带有负电荷的蛋白质,这意味着它在水溶液中带有负电。 这种电荷特性使得EGF能够与正电荷的细胞表面受体结合,从而触发一系列细胞信号传导途径。这些信号传导途径进一步促进了细胞的增殖、...
