Application Abreviews Notes
ICC/IF 1/100 - 1/250.
WB 1/1000. Detects a band of approximately 55 kDa (predicted molecular weight: 44 kDa).
Flow Cyt 1/20. ab172730-Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
IHC-P Use at an assay dependent concentration.
  • Application notesIs unsuitable for IP.
  • Target

    • FunctionParticipates 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 specificityDetected 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 similaritiesBelongs to the TCF/LEF family.
      Contains 1 HMG box DNA-binding domain.
    • DomainProline-rich and acidic regions are implicated in the activation functions of RNA polymerase II transcription factors.
    • Cellular localizationNucleus. Found in nuclear bodies upon PIASG binding.

    • ab53293 staining LEF1 in RAMOS (human Burkitt's lymphoma) cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 4% Paraformaldehyde and permeabilized with 0.1% Triton X-100. Samples were incubated with primary antibody at a dilution of 1/500. A goat anti rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at a dilution of 1/1000. DAPI was used as a nuclear counterstain and the negative control was PBS only.
