PRDM2 (RIZ1) Antibody

Purified Mouse Monoclonal Antibody (Mab)

  • WB - PRDM2 (RIZ1) Antibody AM1194a
    Western blot analysis of anti-PRDM2 Mab (Cat. #AM1194a) in lysate from PRDM2 transgenic lysate.Secondary HRP-anti-mouse was used for signal visualization with chemiluminescence.
  • CHIP - PRDM2 (RIZ1) Antibody AM1194a
    ChIP analysis of estrogen target genes. (A) Soluble chromatin was prepared from MCF7 cells not treated or treated with E2 for 45 min. Immunoprecipitation was performed with antibody against RIZ1 (AM1194a). DNA extractions were amplified by using primer sets that cover the pS2 gene promoter region or the GAPDH gene promoter. Adapted from Fig 6 in Carling et al., 2004 (see citation 2).
  • CHIP - PRDM2 (RIZ1) Antibody AM1194a
    ChIP analysis of estrogen target genes.(B) Time course analysis of RIZ1 binding to the pS2 gene promoter. MCF7 cells treated with E2 for different periods of time, as indicated at the top of each lane, were processed for ChIP analysis. Immunoprecipitation was performed with antibody to RIZ1 (AM1194a) and control immunoglobulin G as indicated. Adapted from Fig 6 in Carling et al., 2004 (see citation 2).
  • CHIP - PRDM2 (RIZ1) Antibody AM1194a
    ChIP analysis of estrogen target genes. (C) ChIP analysis was performed on RIZ1 knockout mouse embryonic fibroblasts by using anti-RIZ1 antibody (AM1194a). Immunoprecipitated chromatin DNA was analyzed by PCR with primers in the G6pd promoter region and in the cdc25c promoter region. Adapted from Fig 6 in Carling et al., 2004 (see citation 2).

Protein Information
Name PRDM2
Synonyms KMT8, RIZ
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.
Cellular Location Nucleus
Tissue Location 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.

This tumor suppressor gene is a member of a nuclear histone/protein methyltransferase superfamily. It encodes a zinc finger protein that can bind to retinoblastoma protein, estrogen receptor, and the TPA-responsive element (MTE) of the heme-oxygenase-1 gene. Although the functions of this protein have not been fully characterized, it may (1) play a role in transcriptional regulation during neuronal differentiation and pathogenesis of retinoblastoma, (2) act as a transcriptional activator of the heme-oxygenase-1 gene, and (3) be a specific effector of estrogen action. Multiple transcript variants encoding different isoforms have been found for this gene.
