High impact information on fzd1-A

 

Biological context of fzd1-A

 

Anatomical context of fzd1-A

  • A role for frizzled 3 in neural crest development [7].
  • The recent discovery that Frizzled proteins are receptor for Wnts has been quickly followed by the identification of a secreted protein, Frzb, that is related to Frizzled, expressed by the Spemann organizer in frog embryos and can bind to and antagonize Wnt developmental signalling molecules [8].
 

Associations of fzd1-A with chemical compounds

  • An expression cloning screen was used to isolate a novel gene homologous to the extracellular cysteine-rich domain of frizzled receptors [9].
  • Since targets of this Ca(2+) release could play a role in Wnt signaling, we first tested the hypothesis that Ca(2+)/calmodulin-dependent protein kinase II (CamKII) is activated by some Wnt and Frizzled homologs [10].
 

Regulatory relationships of fzd1-A

  • Wnt proteins signal through seven-pass transmembrane receptors of the frizzled family to activate beta-catenin-dependent transcription of target genes [6].
 

Other interactions of fzd1-A

  • The maternal Xenopus beta-catenin signaling pathway, activated by frizzled homologs, induces goosecoid in a cell non-autonomous manner [11].
  • To assess the endogenous role of frizzled proteins during vertebrate development, we have identified and characterized a Xenopus frizzled gene (xfz8) [12].
