additional information | in confluent endothelial cells, a fraction of p120-catenin associates and colocalizes with LPP3 at the plasma membrane, via the C-terminal cytoplasmic domain, thereby limiting the ability of LPP3 to stimulate beta-catenin/lymphoid enhancer binding factor 1 signaling | Homo sapiens | - |

malfunction | depletion of LPP3 results in destabilization of beta-catenin, which in turn reduces fibronectin synthesis and deposition, which results in inhibition of endothelial cell migration. Reexpression of beta-catenin but not p120-catenin in LPP3-depleted endothelial cells restores de novo synthesis of fibronectin, which mediates endothelial cell migration and formation of branching point structures. LPP3-RAD mutant, which is defective for integrin binding and a LPP3-PD mutant, which is defective for phosphatase activity stimulate lymphoid enhancer binding factor 1-dependent transcription 3- or 5fold, respectively. The LPP3 mutant that lacks both adhesion and lipid phosphatase domains (hLPP3-RAD+PD) fails to stimulate luciferase activity | Homo sapiens |
physiological function | key role for LPP3 in orchestrating phosphatase and tensin-mediated beta-catenin/lymphoid enhancer binding factor 1 signaling in endothelial cell migration, cell-cell adhesion, and formation of branching point structures. In subconfluent endothelial cells, LPP3 induces expression of fibronectin via beta-catenin/lymphoid enhancer binding factor 1 signaling in a phosphatase and tensin homologue-dependent manner. In confluent endothelial cells, depletion of p120-catenin restores LPP3-mediated beta-catenin/lymphoid enhancer binding factor 1 signaling. In confluent endothelial cells, depletion of p120-catenin restores LPP3-mediated beta-catenin/lymphoid enhancer binding factor 1 signaling. C-terminal domain of LPP3 regulates the expression of p120ctn and VE-cadherin as well as formation of branching point structures. LPP1 and LPP2 have no effect on luciferase (lymphoid enhancer binding factor 1) activity, whereas LPP3 yields an 9fold increase in luciferase activity. LPP1 and LPP2 show no change in basal phosphorylation of beta-catenin | Homo sapiens |
physiological function | LPP3 yields an 8fold increase in luciferase (lymphoid enhancer binding factor 1) activity | Mus musculus |
