MyBioSource.com's TCF7L2 Antibody is a Rabbit Polyclonal antibody. This antibody has been shown to work in applications such as: ELISA, and Western Blot. The TCF7L2 Antibody was generated using TCF7L2 as the antigen and it reacts with Human, Mouse, and Rat.
Description
Function: Participates in the Wnt signaling pathway and modulates MYC expression by binding to its promoter in a sequence-specific manner. Acts as 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 Structure: Interacts with TGFB1I1 (By similarity). Interacts with CTNNB1 (via the armadillo repeat); forms stable transcription complex. 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).
Post-translational Modifications: In vitro, phosphorylated by TNIK. Phosphorylated at Thr-201 and/or Thr-212 by NLK. Phosphorylation by NLK at these sites inhibits DNA-binding by TCF7L2/TCF4, thereby preventing transcriptional activation of target genes of the canonical Wnt/beta-catenin signaling pathway. Polysumoylated. Sumoylation is enhanced by PIAS family members and desumoylation is enhanced by SENP2. Sumoylation/desumoylation regulates TCF7L2/TCF4 transcription activity in the Wnt/beta-catenin signaling pathway without altering interaction with CTNNB1 nor binding to DNA.
Similarity: The promoter-specific activation domain interacts with the transcriptional coactivator EP300. Belongs to the TCF/LEF family
