    • 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.
      Forms transcriptional repressor complexes by associating with MAD, SIN3, YY1 and N-COR. Interacts in the late S-phase of DNA-replication with DNMT1 in the other transcriptional repressor complex composed of DNMT1, DMAP1, PCNA, CAF1. Deacetylates TSHZ3 and regulates its transcriptional repressor activity.
    • Tissue specificity

      Widely expressed; lower levels in brain and lung.
    • Sequence similarities

      Belongs to the histone deacetylase family. HD type 1 subfamily.
    • Post-translational

      S-nitrosylated by GAPDH. In neurons, S-Nitrosylation at Cys-262 and Cys-274 does not affect the enzyme activity but abolishes chromatin-binding, leading to increases acetylation of histones and activate genes that are associated with neuronal development. In embryonic cortical neurons, S-Nitrosylation regulates dendritic growth and branching.

    • Lane 1: Wild type HAP1 whole cell lysate (20 µg)
      Lane 2: HDAC2 knockout HAP1 whole cell lysate (20 µg)
      Lane 3: A431 whole cell lysate (20 µg)
      Lane 4: Hela whole cell lysate (20 µg)

      Lanes 1 - 4: Merged signal (red and green). Green - ab124974 observed at 60 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab124974 was shown to recognize HDAC2 when HDAC2 knockout samples were used, along with additional cross-reactive bands. Wild-type and HDAC2 knockout samples were subjected to SDS-PAGE.  ab124974 and ab8245 (Mouse anti GAPDH loading control) were but diluted at 1/10000 and incubated overnight at 4°C. Blots were developed with 800CW Goat anti Rabbit and 680CW Goat anti Mouse secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.


    • ab124974 staining HDAC2 in wild-type HAP1 cells (top panel) and HDAC2 knockout HAP1 cells (bottom panel). The cells were fixed with 100% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab124974 at 0.5μg/ml and ab195889 at 1/250 dilution (shown in pseudocolour red) overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

      Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

    • Chromatin was prepared from HeLa cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 minutes. The ChIP was performed with 25µg of chromatin, 10µg of ab124974 (blue), and 20µl of Protein A/G sepharose beads. No antibody was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach). Primers and probes are located in the first kb of the transcribed region.
