General annotation (Comments)
| 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 By similarity. Appears be required for postnatal control of vascular regression in the eye. Required for posterior patterning of the epiblast during gastrulation. Ref.5 Ref.7 |
| Subunit structure | Homodimer; disulfide-linked. Forms phosphorylated oligomer aggregates on Wnt-signaling. Component of a WNT-signaling complex that contains a WNT protein, a FZD protein and LRP5 or LRP6. Interacts with FZD8; the interaction is formed on WNT-binding and signaling. Interacts (via the phosphorylated PPPSP motif domains) with AXIN1; the interaction prevents inhibition of beta-catenin phosphorylation and signaling and is enhanced in the presence of GSK3B and WNT1 or WNT3A. Interacts (via beta-propeller regions 3 and 4) with DKK1; the interaction, enhanced by MESD and/or KREMEN, inhibits beta-catenin signaling by preventing GSK3-mediated phosphorylation of the PPPSP motifs and subsequent, AXIN1 binding. Interacts with CSNK1E. Interacts with SOST; the interaction antagonizes canonical Wnt signaling. Interacts with APCDD1 By similarity. Interacts with MESD; the interaction prevents the formation of LRP5 aggregates, targets LRP5 to the plasma membrane and, when complexed with KREMEN2, increases DKK1 binding. Ref.6 |
| Subcellular location | Membrane; Single-pass type I membrane protein. Endoplasmic reticulum. Note: Chaperoned to the plasma membrane by MESD By similarity. Ref.6 |
| Tissue specificity | Widely expressed, with the highest expression levels in liver, heart, and lung and the lowest levels in brain and spleen. Expressed in early embryo with strongest expression in visceral endoderm overlying the extraembryonic ectoderm. Not present in the mesoderm nor in endoderm emerging from the primitive streak. Ref.7 |
| Developmental stage | Expressed before or on embryonic day 7. |
| Post-translational modification | Phosphorylation of cytoplasmic PPPSP motifs regulates the signal transduction of the Wnt signaling pathway through acting as a docking site for AXIN1 By similarity. |
| Disruption phenotype | Mice exhibit decreased osteoblast proliferation, developing low bone mass postnatally. Also display persistent embryonic eye vascularization due to a failure of macrophage-induced endothelial cell apoptosis. LRP5 null mutants exhibit a loss of middle phalanx ossification at 18.5 dpc. Double null LRP5/LRP6 mutants are more severely affected. Embryos arrest prior to mid-gestation. Ref.5 Ref.7 |
| Sequence similarities | Belongs to the LDLR family. Contains 4 EGF-like domains. Contains 3 LDL-receptor class A domains. Contains 20 LDL-receptor class B repeats. |
