[https://www.uniprot.org/uniprot/LRP6_HUMAN LRP6_HUMAN] Component of the Wnt-Fzd-LRP5-LRP6 complex that triggers beta-catenin signaling through inducing aggregation of receptor-ligand complexes into ribosome-sized signalsomes. Cell-surface coreceptor of Wnt/beta-catenin signaling, which plays a pivotal role in bone formation. The Wnt-induced Fzd/LRP6 coreceptor complex recruits DVL1 polymers to the plasma membrane which, in turn, recruits the AXIN1/GSK3B-complex to the cell surface promoting the formation of signalsomes and inhibiting AXIN1/GSK3-mediated phosphorylation and destruction of beta-catenin. Required for posterior patterning of the epiblast during gastrulation (By similarity).<ref>PMID:11448771</ref> <ref>PMID:11357136</ref> <ref>PMID:15778503</ref> <ref>PMID:16341017</ref> <ref>PMID:16513652</ref> <ref>PMID:17400545</ref> <ref>PMID:17326769</ref> <ref>PMID:19107203</ref> <ref>PMID:19801552</ref> <ref>PMID:19293931</ref>

== Publication Abstract from PubMed ==
 +
Wnt morphogens are critical for embryonic development and tissue regeneration. Canonical Wnts form ternary receptor complexes composed of tissue-specific Frizzled (Fzd) receptors together with the shared LRP5/6 coreceptors to initiate beta-catenin signaling. The cryo-EM structure of a ternary initiation complex of an affinity-matured XWnt8-Frizzled8-LRP6 complex elucidates the basis of coreceptor discrimination by canonical Wnts by means of their N termini and linker domains that engage the LRP6 E1E2 domain funnels. Chimeric Wnts bearing modular linker "grafts" were able to transfer LRP6 domain specificity between different Wnts and enable non-canonical Wnt5a to signal through the canonical pathway. Synthetic peptides comprising the linker domain serve as Wnt-specific antagonists. The structure of the ternary complex provides a topological blueprint for the orientation and proximity of Frizzled and LRP6 within the Wnt cell surface signalosome.
