  • Target

    • Function

      Histone deubiquitinating component of the transcription regulatory histone acetylation (HAT) complex SAGA. Catalyzes the deubiquitination of both histones H2A and H2B, thereby acting as a coactivator. Recruited to specific gene promoters by activators such as MYC, where it is required for transcription. Required for nuclear receptor-mediated transactivation and cell cycle progression.
    • Tissue specificity

      Moderately expressed in various tissues including heart and skeletal muscle, and weakly expressed in lung and liver.
    • Sequence similarities

      Belongs to the peptidase C19 family. UBP8 subfamily.
      Contains 1 UBP-type zinc finger.
