应用 Ab评论 说明
WB Use a concentration of 1 - 2 µg/ml. Detects a band of approximately 265 kDa (predicted molecular weight: 265 kDa).Can be blocked with Human KAT3A / CBP peptide (ab4916).
ChIP Use at an assay dependent concentration. PubMed: 20111703

Recommended to be used at 2-4µg for 1-2x106 cells.

IHC-P Use a concentration of 5 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
IP Use at an assay dependent concentration. PubMed: 20403362
CHIPseq Use at an assay dependent concentration. PubMed: 22196736
Inhibition Assay Use at an assay dependent concentration.


  • 功能Acetylates histones, giving a specific tag for transcriptional activation. Also acetylates non-histone proteins, like NCOA3 coactivator. Binds specifically to phosphorylated CREB and enhances its transcriptional activity toward cAMP-responsive genes. Acts as a coactivator of ALX1 in the presence of EP300.
  • 疾病相关Note=Chromosomal aberrations involving CREBBP may be a cause of acute myeloid leukemias. Translocation t(8;16)(p11;p13) with MYST3/MOZ; translocation t(11;16)(q23;p13.3) with MLL/HRX; translocation t(10;16)(q22;p13) with MYST4/MORF. MYST3-CREBBP may induce leukemia by inhibiting RUNX1-mediated transcription.
    Defects in CREBBP are a cause of Rubinstein-Taybi syndrome type 1 (RSTS1) [MIM:180849]. RSTS1 is an autosomal dominant disorder characterized by craniofacial abnormalities, broad thumbs, broad big toes, mental retardation and a propensity for development of malignancies.
  • 序列相似性Contains 1 bromo domain.
    Contains 1 KIX domain.
    Contains 2 TAZ-type zinc fingers.
    Contains 1 ZZ-type zinc finger.
  • 结构域The KIX domain mediates binding to HIV-1 Tat.
  • 翻译后修饰Methylation of the KIX domain by CARM1 blocks association with CREB. This results in the blockade of CREB signaling, and in activation of apoptotic response.
    Phosphorylated upon DNA damage, probably by ATM or ATR.
    Sumoylation negatively regulates transcriptional activity via the recruitment of DAAX.
  • 细胞定位Cytoplasm. Nucleus. Recruited to nuclear bodies by SS18L1/CREST. In the presence of ALX1 relocalizes from the cytoplasm to the nucleus.

Anti-KAT3A / CBP antibody - ChIP Grade 图像

  • Predicted band size : 265 kDa

    ab2832 using HeLa cell lysate.
  • Sonicated chromatin prepared from U2OS cells was subjected to the ChIP procedure with ab2832 to CBP. Immunoprecipitated chromatin was analysed in the promoter region of c-FOS (active) and in exon 2 of MYO-D (inactive). Values are % of inputs.  2–4 µg of ab2832 and 1-2x106 cells were used in each ChIP experiment.

  • IHC image of KAT3A/CBP staining in human pancreas formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab2832, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
