Target

  • Function
    Participates in the Wnt signaling pathway. Activates transcription of target genes in the presence of CTNNB1 and EP300. May play a role in hair cell differentiation and follicle morphogenesis. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by LEF1 and CTNNB1. Regulates T-cell receptor alpha enhancer function. Binds DNA in a sequence-specific manner. PIAG antagonizes both Wnt-dependent and Wnt-independent activation by LEF1 (By similarity). Isoform 3 lacks the CTNNB1 interaction domain and may be an antagonist for Wnt signaling. Isoform 5 transcriptionally activates the fibronectin promoter, binds to and represses transcription from the E-cadherin promoter in a CTNNB1-independent manner, and is involved in reducing cellular aggregation and increasing cell migration of pancreatic cancer cells. Isoform 1 transcriptionally activates MYC and CCND1 expression and enhances proliferation of pancreatic tumor cells.
  • Tissue specificity
    Detected in thymus. Not detected in normal colon, but highly expressed in colon cancer biopsies and colon cancer cell lines. Expressed in several pancreatic tumors and weakly expressed in normal pancreatic tissue. Isoforms 1 and 5 are detected in several pancreatic cell lines.
  • Sequence similarities
    Belongs to the TCF/LEF family.
    Contains 1 HMG box DNA-binding domain.
  • Domain
    Proline-rich and acidic regions are implicated in the activation functions of RNA polymerase II transcription factors.
  • Cellular localization
    Nucleus. Found in nuclear bodies upon PIASG binding.

Images

  • This IHC data was generated using the same anti-LEF1 antibody clone, EPR2029Y, in a different buffer formulation (cat# ab137872).

    Ab137872 staining LEF1 in paraffin embedded Mouse spleen tissue by Immunohistochemistry. Antigen retrieval was by heat mediation using ab93684 (Tris/EDTA buffer, Ph9).  Samples were incubated with primary antibody at 1:2000 dilution. A ready to use Goat Anti-rabbit IgG H&L (HRP) was used as the secondary antibody. Hematoxylin was used as a counter stain. Nuclear staining on T cells in periarterial lymphatic sheath of mouse spleen (PMID: 21685909).
