Low-density lipoprotein receptor-related protein 6 (O75581)

Uniprot ID O75581
Protein Name Low-density lipoprotein receptor-related protein 6
Gene Name LRP6
Species Homo sapiens (Human)
Signal peptide(a) Y Secretome P(b) 0.219
Function 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). .
