CC -!- FUNCTION: Activator of the canonical Wnt signaling pathway by acting as CC a ligand for LGR4-6 receptors. Upon binding to LGR4-6 (LGR4, LGR5 or CC LGR6), LGR4-6 associate with phosphorylated LRP6 and frizzled receptors CC that are activated by extracellular Wnt receptors, triggering the CC canonical Wnt signaling pathway to increase expression of target genes. CC Also regulates the canonical Wnt/beta-catenin-dependent pathway and CC non-canonical Wnt signaling by acting as an inhibitor of ZNRF3, an CC important regulator of the Wnt signaling pathway (PubMed:21727895, CC PubMed:21909076, PubMed:22615920). During embryonic development, plays CC a crucial role in limb specification, amplifying the Wnt signaling CC pathway independently of LGR4-6 receptors, possibly by acting as a CC direct antagonistic ligand to RNF43 and ZNRF3, hence governing the CC number of limbs an embryo should form (PubMed:29769720).
