Rabbit anti-Human LEF1 Polyclonal Antibody

Uniprot Id

Q9UJU2

Target Species

Human

Target Name

LEF1

Target Full Name

Lymphoid enhancer-binding factor 1

Target 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. 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.

Target Background

This gene encodes a transcription factor belonging to a family of proteins that share homology with the high mobility group protein-1. The protein encoded by this gene can bind to a functionally important site in the T-cell receptor-alpha enhancer, thereby conferring maximal enhancer activity. This transcription factor is involved in the Wnt signaling pathway, and it may function in hair cell differentiation and follicle morphogenesis. Mutations in this gene have been found in somatic sebaceous tumors. This gene has also been linked to other cancers, including androgen-independent prostate cancer. Alternative splicing results in multiple transcript variants.
