UniProtKB - F8U830 (NOTUM_SCHMD)
Protein
Palmitoleoyl-protein carboxylesterase NOTUM
Gene
notum
Organism
Schmidtea mediterranea (Freshwater planarian flatworm)
Status
Functioni
Carboxylesterase that acts as a key negative regulator of the Wnt signaling pathway (PubMed:21566195). Acts by specifically mediating depalmitoleoylation of WNT proteins. Serine palmitoleoylation of WNT proteins is required for efficient binding to frizzled receptors (By similarity). Promotes head regeneration following amputation by inhibiting the Wnt signaling pathway.By similarity1 Publication
Catalytic activityi
- [Wnt protein]-O-(9Z)-hexadecenoyl-L-serine + H2O = (9Z)-hexadecenoate + [Wnt protein]-L-serine + H+By similarityEC:3.1.1.98By similarity
