  • General notes

    The retinoblastoma protein is a target of viral oncoproteins. To explore the hypothesis that viral proteins may be structural mimics of cellular RB-binding proteins that normally mediate RB function, Buyse et al. (1995) searched cDNA libraries for RB-binding proteins. They reported the cloning of a cDNA for the zinc finger protein they called RIZ from rat and human cells. It is a 250-kD nuclear protein containing 8 zinc finger motifs. It contains an RB-binding motif that is related to that of the adenovirus E1A oncoprotein; RIZ also shares an antigenic epitope with the C terminus of E1A. It is expressed in human retinoblastoma cells and at low levels in all other human cell lines examined. While the function of RIZ was not clear, its structure and pattern of expression suggested to Buyse et al. (1995) a role in transcriptional regulation during neuronal differentiation and pathogenesis of retinoblastoma.

  • Application notes
    Is unsuitable for ChIP.
  • Target

    • Function
      S-adenosyl-L-methionine-dependent histone methyltransferase that specifically methylates 'Lys-9' of histone H3. May function as a DNA-binding transcription factor. Binds to the macrophage-specific TPA-responsive element (MTE) of the HMOX1 (heme oxygenase 1) gene and may act as a transcriptional activator of this gene.
    • Tissue specificity
      Highly expressed in retinoblastoma cell lines and in brain tumors. Also expressed in a number of other cell lines and in brain, heart, skeletal muscle, liver and spleen. Isoform 1 is expressed in testis at much higher level than isoform 3.
    • Sequence similarities
      Contains 8 C2H2-type zinc fingers.
      Contains 1 SET domain.
