    basic FUNCTION
  • promoting the GSK3B dependent phosphorylation of beta catenin (CTNNB1)
  • negatively regulates both expansion of osteoprogenitors and maturation of osteoblasts through its modulation on Wnt/beta-catenin signaling
  • promotes centrosome cohesion by phosphorylating CTNNB1 at centrosomes (Hadjihannas 2010)
  • negative regulator of beta-catenin, localizes at the centrosomes by binding to the centriole-associated component CEP250
  • essential for normal kinetics of remyelination (
  • serves as a negative regulator of canonical WNT signaling in normal cells
  • tumor suppressor function of AXIN2 in normal cells is most likely coopted by cancer cells to promote, rather than suppress, key aspects of the cancer progression program
  • RUNX2 and AXIN2 regulate craniofacial development and skeletal maintenance
    signaling signal transduction
    negative regulator of the signaling Wnt pathway through interaction with GSK3B and beta catenin
    a component
  • complex of APC, beta catenin, GSK3B
    small molecule
  • glycogen synthase kinase 3beta and beta-catenin (
  • adenomatous polyposis coli and Smad3 (
  • acts as a potent promoter of carcinoma behavior by up-regulating the activity of the transcriptional repressor, SNAI1, inducing a functional epithelial-mesenchymal transition (EMT) program and driving metastatic activity
  • FOXM1 directly bound to and increased transcriptional activity of the AXIN2 promoter region
  • RUNX2 binds several regions of the AXIN2 promoter and RUNX2-mediated repression of AXIN2 transcription depends on HDAC3
  • cell & other
    repressed by RUNX2, HDAC3, that repress AXIN2 transcription in osteoblasts

    frameshift mutations are common in gastric carcinoma with high microsatellite instability (MSI) and may contribute to development of gastric cancers with high MSI by deregulating the Wnt signaling in the affected cancer cells (
