Supplementary information

NOTUM is a lipase-like enzyme that functions mechanically to remove lipid modifications specifically palmitoleate from the Wnt proteins. It is alternatively known as palmitoleoyl-protein carboxylesterase. The molecular mass of NOTUM is approximately 53 kDa. NOTUM is expressed mainly in tissues such as the liver kidneys and gut where it plays a role in regulating signaling pathways.
Biological function summary

NOTUM inhibits the Wnt signaling pathway by cleaving the lipid moiety attached to Wnt proteins making it inactive. NOTUM acts independently and is not part of larger protein complexes. This regulation of Wnt signaling is important for maintaining cellular processes such as cell proliferation differentiation and migration especially during development and tissue homeostasis.

Pathways

NOTUM primarily influences the Wnt signaling pathway. This pathway is significant for embryonic development and adult homeostasis. By inactivating Wnt proteins NOTUM indirectly affects other pathway components like β-catenin which is an important mediator in the Wnt pathway. NOTUM ensures the balance of Wnt signaling preventing overactivation that could lead to abnormal cell growth.

NOTUM's role in regulating Wnt signaling links it to conditions such as colorectal cancer and osteoporosis. In cancers overexpression of NOTUM can contribute to Wnt pathway dysregulation while its inhibition may present a therapeutic angle. In osteoporosis alterations in NOTUM activity can affect bone formation processes through its influence on Wnt-related proteins like LRP5/6. Understanding NOTUM's interactions in these diseases may provide insights into novel treatment strategies.

Target data

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 (PubMed : 25731175).
