Target

  • Function

    Functions as a histone acetyltransferase (HAT) to promote transcriptional activation. Acetylation of histones gives a specific tag for epigenetic transcription activation. Has significant histone acetyltransferase activity with core histones, but not with nucleosome core particles. In case of HIV-1 infection, it is recruited by the viral protein Tat. Regulates Tat's transactivating activity and may help inducing chromatin remodeling of proviral genes. Component of the ATAC complex, a complex with histone acetyltransferase activity on histones H3 and H4.
  • Tissue specificity

    Expressed in all tissues tested, with most abundant expression in ovary.
  • Sequence similarities

    Belongs to the GCN5 family.
    Contains 1 bromo domain.
    Contains 1 N-acetyltransferase domain.
  • Cellular localization

    ab217876 was shown to specifically react with KAT2A in wild type HAP1 cells. No band was observed when KAT2A knockout samples were used. Wild-type and KAT2A knockout samples were subjected to SDS-PAGE. ab217876 and ab181602 (Human anti-GAPDH loading control) were incubated overnight at 4°C at a 1/1000 dilution and 1/5000 dilution respectively. Blots were developed with Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) secondary antibody at 1/100,000 dilution for 1 hour at room temperature before imaging. The blot was developed on a BIO-RAD® ChemiDoc™ MP instrument.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab217876).

  • Chromatin was prepared from A549 treated with thapsigargin (1µM 12 hours) cells according to the Abcam Dual X-ChIP protocol*. Cells were fixed with EGS for 30 minutes, then formaldehyde for 10 minutes.
    The ChIP was performed with 25 µg of chromatin, 5 µg of ab217876 (red), and 20 µl of Protein A/G sepharose beads. 5 µg of rabbit normal IgG was added to the beads control (gray). 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.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab217876).

  • KAT2A / GCN5 was immunoprecipitated from 0.35mg of HeLa (human epithelial cell line from cervix adenocarcinoma) whole cell lysate with ab217876 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab217876 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.

    Lane 1: HeLa whole cell lysate 10ug (Input). 

    Lane 2: ab217876 IP in HeLa whole cell lysate. 

    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab217876 in HeLa whole cell lysate.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
    Exposure time: 30 seconds.
