CC -!- FUNCTION: Activator of the canonical Wnt signaling pathway by acting as
CC a ligand for lgr4-6 receptors, which acts as a key regulator of
CC angiogenesis. Upon binding to lgr4-6 (lgr4, lgr5 or lgr6), lgr4-6
CC associate with phosphorylated lrp6 and frizzled receptors that are
CC activated by extracellular Wnt receptors, triggering the canonical Wnt
CC signaling pathway to increase expression of target genes. Acts both in
CC the canonical. Wnt/beta-catenin-dependent pathway and in non-canonical
CC Wnt signaling pathway. Acts as a key regulator of angiogenesis by
CC controlling vascular stability and pruning: acts by activating the non-
CC canonical Wnt signaling pathway in endothelial cells (By similarity).
CC Can also amplify Wnt signaling pathway independently of LGR4-6
CC receptors, possibly by acting as a direct antagonistic ligand to RNF43
CC and ZNRF3 (By similarity). {ECO:0000250|UniProtKB:Q2TJ95,
CC ECO:0000250|UniProtKB:Q9BXY4}.
CC -!- SUBUNIT: Binds heparin. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:Q2TJ95}.
CC -!- DOMAIN: The FU repeats are required for activation and stabilization of
CC beta-catenin. {ECO:0000250|UniProtKB:Q2TJ95}.
CC -!- SIMILARITY: Belongs to the R-spondin family. {ECO:0000305}.
