Primary gene name(s)LRP6

Protein functionComponent 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. {ECO:0000250, ECO:0000269|PubMed:11357136, ECO:0000269|PubMed:11448771, ECO:0000269|PubMed:15778503, ECO:0000269|PubMed:16341017, ECO:0000269|PubMed:16513652, ECO:0000269|PubMed:17326769, ECO:0000269|PubMed:17400545, ECO:0000269|PubMed:19107203, ECO:0000269|PubMed:19293931, ECO:0000269|PubMed:19801552}.
Subcellular locationCell membrane {ECO:0000269|PubMed:26387593};
Single-pass type I membrane protein. Endoplasmic reticulum {ECO:0000269|PubMed:26387593}. Note=On Wnt signaling, undergoes a cycle of caveolin- or clathrin-mediated endocytosis and plasma membrane location. Released from the endoplasmic reticulum on palmitoylation. Mono-ubiquitination retains it in the endoplasmic reticulum in the absence of palmitoylation. On Wnt signaling, phosphorylated, aggregates and colocalizes with AXIN1 and GSK3B at the plasma membrane in LRP6-signalsomes. Chaperoned to the plasma membrane by MESD, By similarity. {ECO:0000250}.
