  • General notes

    Similar to acetylation and phosphorylation, histone methylation at the N-terminal tail has emerged as an important role in regulating chromatin dynamics and gene activity. Histone methylation occurs on arginine and lysine residues and is catalyzed by two families of proteins, the protein arginine methyltransferase family and the SET-domain-containing methyltransferase family. Five members have been identified in the arginine methyltransferase family. About 27 are grouped into the SET-domain family, and another 17 make up the PR domain family that is related to the SET domain family. The retinoblastoma protein-interacting zinc finger gene RIZ 1 is a tumor suppressor gene and a founding member of the PR domain family. RIZ 1 inactivation is commonly found in many types of human cancers and occurs through loss of mRNA expression, frame shift mutation, chromosomal deletion, and missense mutation. RIZ 1 is also a tumor susceptibility gene in mice. The loss of RIZ 1 mRNA in human cancers was shown to associate with DNA methylation of its promoter CpG island. Methylation of the RIZ 1 promoter strongly correlated with lost or decreased RIZ 1 mRNA expression in breast, liver, colon, and lung cancer cell lines as well as in liver cancer tissues.

  • FunctionS-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 specificityHighly 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 similaritiesContains 8 C2H2-type zinc fingers.
    Contains 1 SET domain.

  • A) Rat B50 brain tumor cell extracts were immunoprecipitated with RIZ antibody or preimmune (Liu L. et al. J. Biol. Chem. 1997. 272: 2984.).

    B) Immunohistochemical analysis of RIZ1 in adenovirus-transduced tumor cells. Established HCT116 xenograft tumors at day 2 after infection of AdRIZ1, Adnull, or buffer alone were processed for RIZ1 in situ detection (TUNEL) analysis (Jiang G-L. and Huang S. Cancer Res. 2001. 61: 1796.)
