The palmitoleoylation of Wnt is required for its binding to Frizzled receptors, which is essential for Wnt signaling activation. NOTUM removes the palmitoleate moiety on Wnt ligands to inactivate Wnt signaling (1,2). The function of NOTUM is dependent on glypicans, which bind both NOTUM and Wnt to co-localize them at the cell surface. NOTUM is expressed in the liver (3), bone (4), epithelial cells in the intestine (5), and brain (6) to regulate tissue formation and function. Biological aging may result from increased NOTUM expression, while inhibition of NOTUM may rejuvenate stem cells to promote tissue regeneration (5). In colorectal cancer and gastric cancer, aberrant high NOTUM expression promotes proliferation and metastasis. Knockdown or inhibition of NOTUM activity suppresses its cancer-promoting effects (7-9). Inhibition of NOTUM activity may represent a new approach to treat disease where aberrant NOTUM activity has been identified as the underlying cause (10).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\n[Wnt protein] O-palmitoleoyl-L-serine hydrolase; hNOTUM; NOTUM; notum pectinacetylesterase homolog; notum pectinacetylesterase homolog (Drosophila); notum, palmitoleoyl-protein carboxylesterase; Palmitoleoyl-protein carboxylesterase NOTUM; Protein notum homolog\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 55,62\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800018768041,"sku":"92654T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-92654t","provider":"Iright","version":"1.0","type":"link"}
