Genet. 19:379-383(1998). CC -!- FUNCTION: Participates in the Wnt signaling pathway and modulates CC MYC expression by binding to its promoter in a sequence-specific CC manner. Acts as repressor in the absence of CTNNB1, and as CC activator in its presence. Activates transcription from promoters CC with several copies of the Tcf motif CCTTTGATC in the presence of CC CTNNB1. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated CC by TCF7L2 and CTNNB1. Expression of dominant-negative mutants CC results in cell-cycle arrest in G1 (By similarity). Necessary for CC the maintenance of the epithelial stem-cell compartment of the CC small intestine. CC -!- SUBUNIT: Binds the armadillo repeat of CTNNB1 and forms a stable CC complex. Binds EP300 (By similarity). CC -!- INTERACTION: CC Q8CE28:Traf1; NbExp=3; IntAct=EBI-646713, EBI-646694; CC -!- SUBCELLULAR LOCATION: Nucleus.

Detected at low levels in heart, lung, CC kidney, pituitary and testis. CC -!- DEVELOPMENTAL STAGE: First detected at E10.5. Highly expressed at CC E13.5-E16.5 in the central nervous system, in particular in the CC roof of the mesencephalon, at the ditelencephalic junction and in CC dorsal thalamus. At E13.5, detected at low levels in CC gastrointestinal epithelia. CC -!- DISEASE: Constitutive activation and subsequent transactivation of CC target genes may lead to the maintenance of stem-cell CC characteristics (cycling and longevity) in cells that should CC normally undergo terminal differentiation and constitute the CC primary transforming event in colorectal cancer (CRC). CC -!- SIMILARITY: Belongs to the TCF/LEF family. CC -!- SIMILARITY: Contains 1 HMG box DNA-binding domain.
