  • Target

    • Function
      Polycomb group (PcG) protein. Component of the PRC2/EED-EZH2 complex, which methylates 'Lys-9' (H3K9me) and 'Lys-27' (H3K27me) of histone H3, leading to transcriptional repression of the affected target gene. The PRC2/EED-EZH2 complex may also serve as a recruiting platform for DNA methyltransferases, thereby linking two epigenetic repression systems. Genes repressed by the PRC2/EED-EZH2 complex include HOXC8, HOXA9, MYT1 and CDKN2A.
    • Tissue specificity
      Overexpressed in breast and colon cancer.
    • Involvement in disease
      Note=A chromosomal aberration involving SUZ12 may be a cause of endometrial stromal tumors. Translocation t(7;17)(p15;q21) with JAZF1. The translocation generates the JAZF1-SUZ12 oncogene consisting of the N-terminus part of JAZF1 and the C-terminus part of SUZ12. It is frequently found in all cases of endometrial stromal tumors, except in endometrial stromal sarcomas, where it is rarer.
    • Sequence similarities
      Belongs to the VEFS (VRN2-EMF2-FIS2-SU(Z)12) family.
      Contains 1 C2H2-type zinc finger.
    • Developmental stage
      Expressed at low levels in quiescent cells. Expression rises at the G1/S phase transition.

    • Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: SUZ12 knockout HAP1 cell lysate (20 µg)

      Lane 4: MCF7 cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab175187 observed at 100 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab175187 was shown to specifically react with SUZ12 in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when SUZ12 knockout samples were used. Wild-type and SUZ12 knockout samples were subjected to SDS-PAGE. ab175187 and ab8245 (loading control to GAPDH) were both 1/1000 and 1/10,000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW)  preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD)  preadsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1hr at room temperature before imaging.
