Our Abpromise guarantee covers the use of ab87978 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 20 kDa.
ELISA Use at an assay dependent concentration.
IHC-P Use a concentration of 1.2 µg/ml. Perform heat mediated antigen retrieval via the microwave method before commencing with IHC staining protocol. Place sample in 1X citrate buffer (pH 6.0) and microwave at 750W for 20 minutes, cool sample subsequently.


  • FunctionTranscriptional coactivator of the p300/CBP-mediated trancription complex. Enhances SMAD-mediated transcription by strengthening the functional link between the DNA-binding SMAD transcription factors and the p300/CBP transcription coactivator complex. Stimulates estrogen-dependent transactivation activity mediated by estrogen receptors signaling; stabilizes the interaction of estrogen receptor ESR1 and histone acetyltransferase EP300. Positively regulates TGF-beta signaling through its association with the SMAD/p300/CBP-mediated transcriptional coactivator complex. Induces transcription from estrogen-responsive promoters and protection against cell death. Potentiates EGR2-mediated transcriptional activation activity from the ERBB2 promoter. Acts as an inhibitor of osteoblastic mineralization through a cAMP-dependent parathyroid hormone receptor signaling. May play a role in pigmentation of melanocytes. Associates with chromatin to the estrogen-responsive TGF-alpha promoter region in a estrogen-dependent manner.
  • Tissue specificityExpressed only in melanocytes and testis.
  • Sequence similaritiesBelongs to the CITED family.
  • Post-translational
    Phosphorylated. Phosphorylation changes in a cell cycle-dependent manner and reduces its transcriptional coactivator activity.
  • Cellular localizationNucleus. Cytoplasm. Shuttles between the nucleus and the cytoplasm by a nuclear export signal and (NES) in a CRM1-dependent manner.

  • Anti-CITED1 antibody (ab87978) at 5 µg/ml + A-431 cell lysate at 50 µg

    Predicted band size : 20 kDa
    Observed band size : 20 kDa
    Additional bands at : 45 kDa. We are unsure as to the identity of these extra bands.
  • All lanes : Anti-CITED1 antibody (ab87978) at 1 µg/ml

    Lane 1 : Transfected 293T cell lysate

    Lysates/proteins at 25 µg per lane.

    Predicted band size : 20 kDa
    Observed band size : 23 kDa (why is the actual band size different from the predicted?)
