靶标

  • 功能

    Nuclear receptor coactivator that directly binds nuclear receptors and stimulates the transcriptional activities in a hormone-dependent fashion. Plays a central role in creating a multisubunit coactivator complex, which probably acts via remodeling of chromatin. Involved in the coactivation of different nuclear receptors, such as for steroids (GR and ER), retinoids (RARs and RXRs), thyroid hormone (TRs), vitamin D3 (VDR) and prostanoids (PPARs). Displays histone acetyltransferase activity. Also involved in the coactivation of the NF-kappa-B pathway via its interaction with the NFKB1 subunit. Interacts with PSMB9.

  • 组织特异性

    Widely expressed. High expression in heart, skeletal muscle, pancreas and placenta. Low expression in brain, and very low in lung, liver and kidney.

  • 序列相似性

    Belongs to the SRC/p160 nuclear receptor coactivator family.
    Contains 1 basic helix-loop-helix (bHLH) domain.
    Contains 1 PAS (PER-ARNT-SIM) domain.

  • 结构域

    Contains three Leu-Xaa-Xaa-Leu-Leu (LXXLL) motifs. Motifs 1 and 2 are essential for the association with nuclear receptors, and constitute the RID domain (Receptor-interacting domain).

  • 翻译后修饰

    Acetylated by CREBBP. Acetylation occurs in the RID domain, and disrupts the interaction with nuclear receptors and regulates its function.
    Methylated by CARM1.
    Phosphorylated by IKK complex. Regulated its function.

  • 细胞定位

    Cytoplasm. Nucleus. Mainly cytoplasmic and weakly nuclear. Upon TNF activation and subsequent phosphorylation, it translocates from the cytoplasm to the nucleus.

      ICC/IF image of ab2831 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab2831, 5µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 WGA was used to label plasma membranes (red).

      ab2831 can be used in ChIP. You can expect recruitment of AIB1on the pS2 promoter at some point during transcriptional activation. The amount of DNA precipiated is significant.

      Sonicated Chromatin prepared from untreated or 17beta-estradiol (E2) treated MCF7 cells was subjected to the ChIP procedure with ab2831 to AIB1 and the immunoprecipitated chromatin was analysed in the proximal region of the estrogen-responsive pS2 promoter (as shown above) and quantified by real-time PCR (values are % of inputs). The primers are designed to follow the nucleosome E (including the Estrogen Responsive Element ERE). 3 µl of ab2831 and 2x106 cells were used in each ChIP experiment.

      IHC image of ab2831 staining in human melanoma 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 ab2831, 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.

No DO YOU OBTAIN THE SAME RESULTS EVERY TIME? Yes WHAT STEPS HAVE YOU ALTERED? I change the dilution from 1:1000 to 1:500 ADDITIONAL NOTES I used the same antibody also in a ChIP experiment and I get also no good results, but in this case it could also be a optimization problem of my ChIP procedure

    Answer

    Thank you for the protocol details that you have provided and I'm sorry to hear that you are experiencing difficulty with ab2831. The antibody was characterized for application in Western blotting using T47D cell lysate and a band at 155 kDa was detected. You certainly are loading a sufficient amount of lysate and a suggestion would be to try using nuclear extract instead of whole cell lysate, but the antibody's originator was able to detect AIB1 in the T47D cell lysate. Just to check - is your secondary antibody working properly with other primaries? There have not been any problems with the batch that you received and it sounds to me as if there may be a problem with the particular that you received. I would be happy to send you a free of charge replacement vial or can issue you a credit note or refund. Please let me know how you would like to proceed and I look forward to hearing from you.
