Misspliced LRP5 mutants have enhanced beta-catenin-dependent signaling

Locations in the PathwayBrowser

LRP5 is subject to an in-frame missplicing event in breast and parathyroid cancers that renders the protein insensitive to inhibition by the WNT antagonist DKK1. Expression of the mutant protein results in elevated levels of active, unphosphorylated beta-catenin and enhanced TCF-dependent WNT-signaling, promoting cellular proliferation (Bjorklund et al 2007a, b; Bjorklund et al, 2009).
