    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • inhibiting TBP-driven RNA polymerase II and III transcription
  • removing TBP from DNA (TATA box) in an ATP-dependent manner
  • ATP-dependent helicase regulating TBP function on POLII promoters in cells
  • Swi2/Snf2 enzyme that specifically displaces TBP from the promoter DNA and regulates transcription globally by generating a highly dynamic TBP pool in the cell
  • TBP, BTAF1, and DR1 establish a regulatory circuit that controls downstream core promoter element-dependent versus TATA-dependent transcription b
  • negatively regulates TBP and DR1 binding to active promoters
  • not only displaces TBP, but blocks its hydrophobic surface patch to prevent interactions with DNA or other factors that bind to the concave surface
