NOTUM
(WNT SIGNALING) LIBRARY

NOTUM
(WNT SIGNALING) LIBRARY


ChemDiv presents a brand new library – NOTUM (Wnt Signaling) Library, which consists of over 4,000 compounds.

NOTUM is a carboxylesterase that has been shown to act by mediating the O-depalmitoleoylation of Wnt proteins resulting in suppression of Wnt signaling. Members of the Wnt family are secreted signaling proteins that play key roles in adult stem cell biology as well as in embryonic development.

Conversely, dysregulation of Wnt signaling is frequently associated with growth-related pathologies and cancers, particularly those of tissues for which Wnts normally stimulate self-renewal and repair. Wnt signaling is also implicated to have a role in neurodegenerative diseases such as Alzheimer’s disease. O-Palmitoleoylation of a conserved serine residue in Wnt proteins is a key post-translation modification required for efficient binding of Wnt proteins to Frizzled receptors, a requirement for signal transduction.

A carboxylesterase NOTUM was previously shown to antagonize Wnt signaling pathways. More recently, NOTUM has been shown to act by mediating the depalmitoleoylation of Wnt proteins resulting in suppression of Wnt signaling. It follows that inhibition of NOTUM could restore Wnt signaling with potential benefit in diseases where Wnt deficiency is an underlying cause.

This library is available for immediate shipping and could be conveniently formatted in any type of 96- or 384-well plates: https://store.chemdiv.com/catalog/focused_and_targeted_libraries/notum_wnt_signaling_library
