    basic FUNCTION
  • transcriptional activator through interaction with the transcription elongation factor TCEA1
  • capacity to immortalize hematopoietic cells when fused with MLL
  • apoptosis inducer (caspase dependent) in prostate cancer cells, growth inhibitory leading to tumor suppression
  • strong positive regulator of ELL elongation activity
  • playing a role in regulation of RNA polymerase II transcription
  • can modulate HIF1alpha and angiogenesis, possibly via direct binding and stabilization of VHL (Xiao 2009)
  • regulates the expression of TSP1 via blocking TP53 repression of the TSP1 promoter (Su 2010)
  • CELLULAR PROCESS nucleotide, transcription, regulation
    a component
    small molecule
  • interacting with ELL, ELL2
  • interacting with TCEA1
  • interacting with TFPT (TFPT is an important binding partner and a functional regulator of U19/EAF2, EAF1, and/or ELL)(Jiang 2007)
