Disease relevance of Fzd1

 

High impact information on Fzd1

  • G protein signaling from activated rat frizzled-1 to the beta-catenin-Lef-Tcf pathway [4].
  • The central effector of the Wnt pathway is beta-catenin, which undergoes stabilization upon binding of Wnt ligands to frizzled receptors [5].
  • Biochemical analysis demonstrates that Wnt7b can bind to Fzd1 and -10 on the cell surface and cooperatively activate canonical Wnt signaling with these receptors in the presence of LRP5 [6].
  • Fzd1, -4, and -7 are expressed primarily in the developing lung mesenchyme, and Fzd10 is expressed in airway epithelium [6].
  • Identification and cloning of a secreted protein related to the cysteine-rich domain of frizzled. Evidence for a role in endothelial cell growth control [7].
 

Biological context of Fzd1

  • In the course of the analysis of genes regulated by bone morphogenetic protein 2 in mesenchymal cells we found a significant induction of murine Frizzled-1 (mFz1) gene expression [8].
  • Asymmetric localization of Vangl2 and Fz3 indicate novel mechanisms for planar cell polarity in mammals [9].
  • WNT factors represent key mediators of many processes in animal development and homeostasis and act through a receptor complex comprised of members of the Frizzled and low density lipoprotein-related receptors (LRP) [10].
  • Our results indicated that activated Fz1 increases stability of beta-catenin, inhibits apoptosis, induces osteoblastogenesis, and inhibits adipogenesis [11].
  • The expression of eight murine Frizzled (1,3-9) genes was studied during mouse somitogenesis, in order to correlate the Wnt-dependent activation of myogenesis with the expression of specific Frizzled putative receptors [12].
 

Anatomical context of Fzd1

  • We report comprehensive analysis of Wnt and Fz expression in whole liver as well as individual cell types: freshly isolated and plated hepatocytes, biliary epithelial cells, normal and activated stellate and Kupffer cells, and sinusoidal endothelial cells (SECs) [13].
  • The same 14 Wnt and 7 Fz genes were expressed in both activated and normal stellate and Kupffer cells; only Fzb was expressed in their activated state [13].
  • Although only 6 Wnt and 5 Fz genes were expressed in freshly isolated hepatocytes, 8 Wnt genes, 7 Fz genes, and Fzb were expressed in plated hepatocytes [13].
  • We found that sFRP3 unexpectedly increased osteoblast differentiation, suggesting it may act through other mechanisms besides acting as a decoy receptor for Wnt's. INTRODUCTION: Secreted frizzled-related proteins (sFRPs) are a truncated form of frizzled receptor, missing both the transmembrane and cytosolic domains [14].
  • Collectively these findings suggest (1) a functional role for Wnt-producing thymic epithelium in determining TCF/LEF-mediated transcriptional regulation in Fz-bearing thymocytes, and (2) a role for defined Wnt-Fz interactions at successive stages of thymocyte maturation [15].
 

Associations of Fzd1 with chemical compounds

  • By using chimeric constructs in which N- and C-terminal segments of mFz1 were replaced by the corresponding parts of Xfz3 we demonstrated that the antagonistic activity resides in the cysteine-rich domain of the N-terminal part [8].
  • Wnt signaling, Ca2+, and cyclic GMP: visualizing Frizzled functions [16].
  • The results show that the main families in the human genome, Glutamate, Rhodopsin, Adhesion, Frizzled, and Secretin, arose before the split of nematodes from the chordate lineage [17].
 

Physical interactions of Fzd1

  • Our results in combination with work from Xenopus laevis (not shown) lead us to believe that Wnt-4 binds both canonical and noncanonical Frizzled receptors, thereby activating Wnt signaling pathways that may each contribute to kidney tubulogenesis [18].
 

Regulatory relationships of Fzd1

 

Other interactions of Fzd1

  • Wnts are extracellular ligands that bind to frizzled (Fz) receptors at the membrane, canonically inducing beta-catenin nuclear translocation and activation [13].
  • Although 12 Wnt and 7 Fz genes were expressed in biliary tree, additional Fz9 and Fzb were only expressed in cultured biliary epithelial cells [13].
  • Oligonucleotides for the 19 Wnt, 10 frizzled receptors genes, and secreted Frizzled-related protein-1 (sFRP or Fzb) were synthesized based on the available sequences [13].
  • Thus, casein kinase 2 is shown to be regulated by Wnt3a and essential to stimulation of the Frizzled-1/beta-catenin/Lef-Tcf pathway [19].
  • We ectopically expressed constitutively active chimeras between Wnt8 and Fz1 or Fz2 in preadipocytes and mesenchymal precursor cells [11].
