Usage
For Research Use Only. Not for use in diagnostic or therapeutic procedures.
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. May play a role in hair cell differentiation and follicle morphogenesis.; Transcriptionally activates MYC and CCND1 expression and enhances proliferation of pancreatic tumor cells.; Lacks the CTNNB1 interaction domain and may therefore be an antagonist for Wnt signaling.; 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.
