Function

Participates in the Wnt signaling pathway and modulates MYC expression by binding to its promoter in a sequence-specific manner. Acts as a repressor in the absence of CTNNB1, and as activator in its presence. Activates transcription from promoters with several copies of the Tcf motif 5'-CCTTTGATC-3' in the presence of CTNNB1.

Biological Context

Subcellular Location: Nucleus, PML body; Nucleus
Tissue Specificity: Detected in epithelium from small intestine, with the highest expression at the top of the crypts and a gradient of expression from crypt to villus. Detected in colon epithelium and colon cancer, and in epithelium from mammary gland and carcinomas derived therefrom
Disease Association: [Constitutive activation and subsequent transactivation of target genes may lead to the maintenance of stem-cell characteristics (cycling and longevity) in cells that should normally undergo terminal differentiation and constitute the primary transforming event in colorectal cancer (CRC)] | Type 2 diabetes mellitus (T2D) : A multifactorial disorder of glucose homeostasis caused by a lack of sensitivity to insulin. Affected individuals usually have an obese body habitus and manifestations of a metabolic syndrome characterized by diabetes, insulin resistance, hypertension and hypertriglyceridemia. The disease results in long-term complications that affect the eyes, kidneys, nerves, and blood vessels. [Disease susceptibility is associated with variants affecting the gene represented in this entry]

Function

Participates in the Wnt signaling pathway and modulates MYC expression by binding to its promoter in a sequence-specific manner. Acts as a repressor in the absence of CTNNB1, and as activator in its presence. Activates transcription from promoters with several copies of the Tcf motif 5'-CCTTTGATC-3' in the presence of CTNNB1. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by TCF7L2/TCF4 and CTNNB1. Expression of dominant-negative mutants results in cell-cycle arrest in G1. Necessary for the maintenance of the epithelial stem-cell compartment of the small intestine

Subunit

Interacts with TGFB1I1 (By similarity). Interacts with CTNNB1 (via the armadillo repeat); forms stable transcription complex (PubMed:10080941, PubMed:17052462, PubMed:19816403, PubMed:28829046, PubMed:29739711, PubMed:9065401, PubMed:9916915). Interacts with EP300. Interacts with NLK. Interacts with CCDC85B (probably through the HMG box); prevents interaction with CTNNB1. Interacts with TNIK. Interacts with MAD2L2; prevents TCF7L2/TCF4 binding to promZIPK/DAPK3oters, negatively modulating its transcriptional activity. Interacts with ZIPK/DAPK3. Interacts with XIAP/BIRC4 and TLE3. Interacts with DDIT3/CHOP. The CTNNB1 and TCF7L2/TCF4 complex interacts with PML (isoform PML-4). Identified in a complex with CTNNB1 and FERMT2. Interacts with SPIN1 (PubMed:22258766, PubMed:24589551, PubMed:29061846). Interacts with C11orf84/SPINDOC in a SPIN1-dependent manner (PubMed:29061846). Interacts with DAZAP2; the interaction results in localization of DAZAP2 to the nucleus (PubMed:19304756)
