Target

  • Function

    Histone methyltransferase that specifically trimethylates 'Lys-9' of histone H3 using monomethylated H3 'Lys-9' as substrate. H3 'Lys-9' trimethylation represents a specific tag for epigenetic transcriptional repression by recruiting HP1 (CBX1, CBX3 and/or CBX5) proteins to methylated histones. Mainly functions in heterochromatin regions, thereby playing a central role in the establishment of constitutive heterochromatin at pericentric and telomere regions. H3 'Lys-9' trimethylation is also required to direct DNA methylation at pericentric repeats. SUV39H1 is targeted to histone H3 via its interaction with RB1 and is involved in many processes, such as cell cycle regulation, transcriptional repression and regulation of telomere length. May participate in regulation of higher order chromatin organization during spermatogenesis.
  • Sequence similarities

    Belongs to the histone-lysine methyltransferase family. Suvar3-9 subfamily.
    Contains 1 chromo domain.
    Contains 1 post-SET domain.
    Contains 1 pre-SET domain.
    Contains 1 SET domain.
  • Domain

    Although the SET domain contains the active site of enzymatic activity, both pre-SET and post-SET domains are required for methyltransferase activity. The SET domain also participates to stable binding to heterochromatin.
  • Cellular localization

    Nucleus. Chromosome > centromere. Associates with centromeric constitutive heterochromatin.

    Lanes 1 - 4: Merged signal (red and green). Green - ab190870 observed at 47 kDa. Red - loading control, ab8245, observed at 37 kDa.

    ab190870 was shown to recognize SUV39H2 in wild-type U2-OS cells as signal was lost at the expected MW in SUV39H2 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and SUV39H2 knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% Milk. Ab190870 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
