CC   -!- FUNCTION: Ligand for members of the frizzled family of seven
CC       transmembrane receptors. Functions in the canonical Wnt signaling
CC       pathway that results in activation of transcription factors of the
CC       TCF/LEF family. Required for normal embryonic mesoderm development and
CC       formation of caudal somites. Required for normal morphogenesis of the
CC       developing neural tube. {ECO:0000250|UniProtKB:P27467,
CC       ECO:0000250|UniProtKB:P56704}.
CC   -!- SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular
CC       matrix {ECO:0000250|UniProtKB:P27467}. Secreted
CC       {ECO:0000250|UniProtKB:P27467}.
CC   -!- PTM: Disulfide bonds have critical and distinct roles in secretion and
CC       activity. Loss of each conserved cysteine results in high molecular
CC       weight oxidized Wnt oligomers, which are formed through inter-Wnt
CC       disulfide bonding. {ECO:0000250|UniProtKB:P27467}.
CC   -!- PTM: Palmitoleoylation is required for efficient binding to frizzled
CC       receptors. Depalmitoleoylation leads to Wnt signaling pathway
CC       inhibition. {ECO:0000250|UniProtKB:P27467,
CC       ECO:0000250|UniProtKB:P56704}.
CC   -!- SIMILARITY: Belongs to the Wnt family. {ECO:0000305}.
