CC -!- FUNCTION: Carboxylesterase that acts as a key negative regulator of the CC Wnt signaling pathway by specifically mediating depalmitoleoylation of CC WNT proteins. Serine palmitoleoylation of WNT proteins is required for CC efficient binding to frizzled receptors (PubMed:25731175). Also acts as CC a regulator of long-range activity of Hedgehog (hh), possibly by CC regulating the switch between low and high level hh pathway signaling CC (PubMed:20412775, PubMed:22872085). {ECO:0000250|UniProtKB:Q6P988, CC ECO:0000269|PubMed:20412775, ECO:0000269|PubMed:22872085, CC ECO:0000269|PubMed:25731175}. CC -!- CATALYTIC ACTIVITY: CC Reaction=[Wnt protein]-O-(9Z)-hexadecenoyl-L-serine + H2O = (9Z)- CC hexadecenoate + [Wnt protein]-L-serine + H(+); Xref=Rhea:RHEA:45340, CC Rhea:RHEA-COMP:11170, Rhea:RHEA-COMP:11171, ChEBI:CHEBI:15377, CC ChEBI:CHEBI:15378, ChEBI:CHEBI:29999, ChEBI:CHEBI:32372, CC ChEBI:CHEBI:85189; EC=3.1.1.98; CC Evidence={ECO:0000250|UniProtKB:Q6P988}; CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:12000788, CC ECO:0000269|PubMed:12015973, ECO:0000269|PubMed:25731175}. Cell surface CC {ECO:0000269|PubMed:25731175}. Note=Associates with the cell surface CC via interaction with sulfated CAG chains on glypicans. CC {ECO:0000269|PubMed:25731175}. CC -!- INDUCTION: Expression is induced by Wnt. {ECO:0000269|PubMed:12000788, CC ECO:0000269|PubMed:12015973}. CC -!- SIMILARITY: Belongs to the pectinacetylesterase family. Notum CC subfamily. {ECO:0000305}. CC -!- CAUTION: The molecular function of NOTUM has remained unclear for many CC years. It was initially thought to hydrolyze glycosaminoglycan (GAG) CC chains of glypicans, thereby affecting glypicans ability to interact CC with Wnt ligands (PubMed:12015973, PubMed:12000788). It was later CC reported to trigger glypican shedding, by mediating cleavage of their CC GPI-anchor (PubMed:15469839). However, while NOTUM specifically inhibit CC the Wnt signaling pathway, more pleiotropic effects would be expected CC from an enzyme affecting glypicans. It was finally shown that it CC requires glypicans to suppress Wnt signaling, but does not cleave their CC GPI-anchor (PubMed:25731175). It acts by mediating depalmitoleoylation CC of WNT proteins, impairing WNT binding to frizzled receptors CC (PubMed:25731175). {ECO:0000269|PubMed:25731175, CC ECO:0000305|PubMed:12000788, ECO:0000305|PubMed:12015973, CC ECO:0000305|PubMed:15469839}.
