Target Bioclass
Enzyme
Family
Pectinacetylesterase family, Notum subfamily
Subcellular location
Secreted
Function
Carboxylesterase that acts as a key negative regulator of the Wnt signaling pathway by specifically mediating depalmitoleoylation of WNT proteins. Serine palmitoleoylation of WNT proteins is required for efficient binding to frizzled receptors.
