[[http://www.uniprot.org/uniprot/ZNRF3_MOUSE ZNRF3_MOUSE]] E3 ubiquitin-protein ligase that acts as a negative regulator of the Wnt signaling pathway by mediating the ubiquitination and subsequent degradation of Wnt receptor complex components Frizzled and LRP6. Acts on both canonical and non-canonical Wnt signaling pathway. Acts as a tumor suppressor in the intestinal stem cell zone by inhibiting the Wnt signaling pathway, thereby resticting the size of the intestinal stem cell zone.<ref>PMID:22575959</ref> <ref>PMID:22895187</ref> [[http://www.uniprot.org/uniprot/RSPO2_XENTR RSPO2_XENTR]] Activator of the canonical Wnt signaling pathway by acting as a ligand for lgr4-6 receptors. Upon binding to lgr4-6 (lgr4, lgr5 or lgr6), lgr4-6 associate with phosphorylated lrp6 and frizzled receptors that are activated by extracellular Wnt receptors, triggering the canonical Wnt signaling pathway to increase expression of target genes. Acts both in the canonical. Wnt/beta-catenin-dependent pathway and in non-canonical Wnt signaling pathway. Activates neural markers and promotes muscle formation. Overexpression blocks activin, nodal and BMP4 signaling, suggesting that it may negatively regulate the TGF-beta pathway (By similarity).
