    text
  • nuclear retention of TLE proteins requires HHEX to bind to both TLE and DNA
  • subnuclear localization of TLE1 plays an important role in transcriptional repression by HHEX
    • basic FUNCTION
  • negative regulator of CBFA2 (AML1)
  • may be a cofactor in ERR-gamma-mediated transcriptional regulation
  • transcriptional corepressor that inhibits Wnt signaling and other cell fate determination signals, and so have an established role in repressing differentiation
  • functions with RUNX2 in epigenetic repression of ribosomal RNA genes
  • with RUNX2, and UBTF together occupy nucleolar organizing regions (NORs) during mitosis and control histone modifications
  • might plays roles independently of HESX1 by interacting with other transcription factors
  • co-repressor that involves many signaling pathways like cell survival, hematopoiesis and differentiation
  • critical factor for the survival of synovial sarcomas
  • plays a critical role in the regulation of neurogenesis by inhibiting the differentiation of neural progenitor cells into neurons
  • is necessary for the maintenance of neuronal survival
  • Groucho-related transcriptional repressor protein that exerts survival and antiapoptotic function in several cellular systems and has been implicated in the pathogenesis of cancer
  • regulator of anoikis in normal mammary epithelial and breast carcinoma cells
  • novel role for TLE1 in the maintenance of anoikis resistance in breast cancer cells

  • coexpressed with NOTCH implicating these molecules in the maintenance of the undifferentiated state in epithelial cells
  • interacting with ERR-gamma
  • associates with rRNA genes during mitosis and interphase through interaction with RUNX2
  • interacting with HESX1 and repressing PROP1 activity
  • TLE1 cooperates with FOXG1 to promote neuronal survival in a CK2- and PI3K-AKT-dependent manner
