The interaction of secreted proteins Noggin4 and Wnt8 from Xenopus laevis embryos

详细

We demonstrated that the secreted protein Noggin4 from Xenopus laevis was capable of the in vitro binding to the secreted factor Wnt8, one of the ligands of the Wnt/betaCatenin signaling pathway. It was also shown that posttranslational modifications occurring during secretion of these proteins from the embryonic cells were necessary for their effective interaction. Also, we proposed a method for the preparation of physiologically active secreted morphogenic proteins from the intercellular space of the Xenopus laevis embryos.
