    basic FUNCTION
  • inhibitor of class II and III genes transcription
  • controls TBP binding and maintenance on DNA that is largely independent of a canonical TATA sequence
  • represses both basal and activated levels of transcription
  • physiologically involved in the control of cell proliferation
  • inhibiting the assembly of the preinitiation complex and controling the rate of RNA polymerase II transcription
  • specifically involved in neuroblastoma pathogenesis and may be considered a new neuroblastoma biomarker
  • TBP, BTAF1, and DR1 establish a regulatory circuit that controls downstream core promoter element-dependent versus TATA-dependent transcription b
  • BTAF1 and DR1 predominantly affect TBP dissociation rates, leaving the association rate unchanged
  • CELLULAR PROCESS nucleotide, transcription, regulation
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • heterodimer with DRAP1
  • forms a stable complex with TATA-binding protein (TBP) on promoters
  • INTERACTION
    DNA binding to TATA-box (TBP)
    RNA
    small molecule
    protein BTAF1 negatively regulates TBP and DR1 binding to active promoters
