  • Application notes
    Is unsuitable for ICC.
  • Target

    • Function
      Multifunctional transcription factor that exhibits positive and negative control on a large number of cellular and viral genes by binding to sites overlapping the transcription start site. May play an important role in development and differentiation. The function of YY1 as an activator or a repressor is specified by the presence of other proteins. For example it acts as a repressor in absence of adenovirus E1A protein but as an activator in its presence.
    • Sequence similarities
      Belongs to the YY transcription factor family.
      Contains 4 C2H2-type zinc fingers.
    • Cellular localization
      Nucleus matrix. Associated with the nuclear matrix.
