  • Target

    • Function
      The association of the DR1/DRAP1 heterodimer with TBP results in a functional repression of both activated and basal transcription of class II genes. This interaction precludes the formation of a transcription-competent complex by inhibiting the association of TFIIA and/or TFIIB with TBP. Can bind to DNA on its own. Component of the ATAC complex, a complex with histone acetyltransferase activity on histones H3 and H4.
    • Sequence similarities
      Belongs to the NC2 beta/DR1 family.
      Contains 1 histone-fold domain.
    • Post-translational
      Phosphorylation regulates its interaction with TBP. Not phosphorylated when bound to DRAP1.
