Publication number: 20120178747Abstract: The mechanism by which the high bone mass (HBM) mutation (G171V) of the Wnt coreceptor LRP5 regulates the canonical Wnt signaling was investigated. The mutation was previously shown to reduce Dkk protein-1-mediated antagonism, suggesting that the first YWTD repeat domain where G171 is located may be responsible for Dkk protein-mediated antagonism. However, we found that the third YWTD repeat, but not the first repeat domain, is required for DKK1-mediated antagonism. Instead, we found that the G171V mutation disrupted the interaction of LRP5 with Mesd, a chaperon protein for LRP5/6 that is required for the coreceptors' transport to cell surfaces, resulting in less LRP5 molecules on the cell surface. Although the reduction in the level of cell surface LRP5 molecules led to a reduction in Wnt signaling in a paracrine paradigm, the mutation did not appear to affect the activity of coexpressed Wnt in an autocrine paradigm.Type: ApplicationFiled: November 14, 2006Publication date: July 12, 2012Inventors: Dianqing (Dan) Wu, Dakai Liu, James J.
