Target

  • Function
    Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. May play a role in smooth muscle cell contractility.
  • Tissue specificity
    Weakly expressed in most tissues. Expressed at higher level in heart, brain, kidney and pancreas and also in liver, lung, placenta, prostate and kidney.
  • Sequence similarities
    Belongs to the histone deacetylase family. HD type 1 subfamily.
  • Post-translational
    modifications
    Phosphorylated by PKA on serine 39. Phosphorylation reduces deacetylase activity observed preferentially on histones H3 and H4.
  • Cellular localization
    Nucleus. Cytoplasm. Excluded from the nucleoli. Found in the cytoplasm of cells showing smooth muscle differentiation.

  • Lane 1: Wild-type HAP1 cell lysate (20 µg)
    Lane 2: HADC8 knockout HAP1 cell lysate (20 µg)
    Lane 3: K562 cell lysate (20 µg)
    Lane 4: HeLa cell lysate (20 µg)
    Lanes 1 - 4: Merged signal (red and green). Green - ab187139. Red - loading control, ab7291, observed at 52 kDa.
    ab187139 was shown to specifically react with HDAC8 when HDAC8 knockout samples were used. Wild-type and HDAC8 knockout samples were subjected to SDS-PAGE. ab187139 and ab7291 (loading control to alpha tubulin) were diluted 1/10 000 and 1/2000 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 1 h at room temperature before imaging.

  • Immunoprecipitation analysis of human fetal kidney tissue lysate labeling HDAC8 using ab187139 at 1/50 dilution (Lane 1). Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG at 1/1500 was used as secondary antibody. Lane 2: PBS instead of human fetal kidney tissue lysate.

  • Flow cytometry analysis of K562 cells labeling HDAC8 using ab187139 at 1/150 dilution. A Goat anti rabbit IgG (FITC) at 1/150 dilution was used as secondary antibody. Cells were fixed with 2% paraformaldehyde. Isotype control: Rabbit monoclonal IgG.
