Post Translational Modifications | Phosphorylated at Thr-155 and/or Ser-166 by NLK. Phosphorylation by NLK at these sites represses LEF1-mediated transcriptional activation of target genes of the canonical Wnt signaling pathway. |
Function | Transcription factor that binds DNA in a sequence-specific manner. Participates in the Wnt signaling pathway. Activates transcription of target genes in the presence of CTNNB1 and EP300. PIAG antagonizes both Wnt-dependent and Wnt-independent activation by LEF1. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by LEF1 and CTNNB1. Regulates T-cell receptor alpha enhancer function. Required for IL17A expressing gamma-delta T-cell maturation and development, via binding to regulator loci of BLK to modulate expression. Acts as a positive regulator of odontoblast differentiation during mesenchymal tooth germ formation, expression is repressed during the bell stage by MSX1-mediated inhibition of CTNNB1 signaling. May play a role in hair cell differentiation and follicle morphogenesis. Isoform 1: Transcriptionally activates MYC and CCND1 expression and enhances proliferation of pancreatic tumor cells. Isoform 3: Lacks the CTNNB1 interaction domain and may therefore 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. |
