LDL-related proteins LRP-5 and LRP-6. are members of the LDL receptor superfamily, which were found to be involved in the canonical Wnt signaling pathway. Mammalian LRP-6 was shown to bind to Wnt-1 and enhance Induced-induced developmental processes in Xenopus embryos. Mice lacking LRP-6 exhibited developmental defects that are similar to those caused by deficiencies in various Want proteins. Recent work also shows that Want proteins induce the binding of LRP-5 to Axin, leading Axin degradation and
