Application Abreviews Notes
  • Application notes
    WB: Use at a concentration of 1 - 3 µg/ml. Detects a band of approximately 30 kDa in Mouse Spleen lysate.
    (predicted molecular weight: 28 kDa).

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function
      Transcriptional coactivator that specifically associates with either OCT1 or OCT2. It boosts the OCT1 mediated promoter activity and to a lesser extent, that of OCT2. It has no intrinsic DNA-binding activity. It recognizes the POU domains of OCT1 and OCT2. It is essential for the response of B-cells to antigens and required for the formation of germinal centers.
    • Tissue specificity
      B-cell specific.
    • Involvement in disease
      Note=A chromosomal aberration involving POU2AF1/OBF1 may be a cause of a form of B-cell leukemia. Translocation t(3;11)(q27;q23) with BCL6.
    • Sequence similarities
      Belongs to the POU2AF1 family.
    • Post-translational
      Ubiquitinated; mediated by SIAH1 or SIAH2 and leading to its subsequent proteasomal degradation.
