  • Function

    Binds to and inhibits the transcriptional repressor ZBTB33, which may lead to activation of target genes of the Wnt signaling pathway (By similarity). May associate with and regulate the cell adhesion properties of both C- and E-cadherins. Implicated both in cell transformation by SRC and in ligand-induced receptor signaling through the EGF, PDGF, CSF-1 and ERBB2 receptors. Promotes GLIS2 C-terminal cleavage.
  • Tissue specificity

    Expressed in vascular endothelium.
  • Sequence similarities

    Belongs to the beta-catenin family.
    Contains 10 ARM repeats.
  • Domain

    A possible nuclear localization signal exists in all isoforms where Asp-626--631-Arg are deleted.
  • Post-translational

    Phosphorylated by protein-tyrosine kinases. Dephosphorylated by PTPRJ.
  • Cellular localization

    Cytoplasm. Nucleus. Cell membrane. Interaction with GLIS2 promotes nuclear translocation (By similarity). NANOS1 induces its translocation from sites of cell-cell contact to the cytoplasm.

Customer reviews and Q&As

1-2 of 2 Abreviews or Q&A


I have contacted the laboratory who tested the protocol, and they have kindly provided the following general protocol which has been used. The antibody was tested some time ago but they probably used 0.01M Sodium Citrate Buffer (pH 6.0 antigen retrieval buffer at that time. Please note that the protocol including the antibody dilution and suggested antigen retrieval would be a guideline only and may require some further optimization. For antibody dilution, we usually suggest a titration experiment using different dilutions to help optimize (e.g start with 1:100, 1:500, 1:1000).

I hope this will be helpful. Please do not hesitate to contact me if you require any further information.
