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 Wnt-induced developmental processes in Xenopus embryos. Mice lacking LRP 6 exhibited developmental defects that are similar to those caused by deficiencies in various Wnt proteins. Recent work also shows that Wnt proteins induce the binding of LRP 5 to Axin, leading Axin degradation and beta catenin stabilization.
