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.

Anti-LEF1 antibody (ab74549) at 1 µg/ml + Jurkat (Human T cell lymphoblast-like cell line) Whole Cell Lysate at 10 µg
Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 44 kDa
Observed band size: 42 + 50 kDa why is the actual band size different from the predicted?
Additional bands at: 15 kDa, 71 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 10 minutes
ab74549 detects a band at 42 and 50 kDa. While this differs to its predicted molecular weight of 44 kDa, this migration has been observed in the literature PMID:17335794.
