Cellular Localization

Antigen Cellular Localization: Membrane; Single-pass type I membrane protein. Endoplasmic reticulum. 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).

Host

Rabbit

Species Reactivity

Human

Target

A phospho specific peptide corresponding to residues surrounding serine 1490 of human LRP6 was used as an immunogen. This antibody detects LRP6 phosphorylated on serine 1490.

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).

Summary

LRP6 (low-density lipoprotein receptor-related protein 6) is a single span transmembrane Wnt receptor that interacts with Axin to promote the Wnt-dependent accumulation of beta-catenin. Cells treated with Wnt quickly induce plasma membrane-associated LRP6 aggregates. The aggregates are phosphorylated, and then promote Axin recruitment and beta-catenin stabilization. LRP6 is internalized with caveolin and components of this endocytic pathway are required not only for Wnt-3a-induced internalization of LRP6 but also for accumulation of beta-catenin. Wnt-3a triggers the interaction of LRP6 with caveolin and promotes recruitment of Axin to LRP6 phosphorylated at Serine 1490 by glycogen synthase kinase-3beta (1-2).
