Application Abreviews Notes
  • Application notes
    WB: Use at a concentration of 1 µg/ml. Detects a band of approximately 35 kDa (predicted molecular weight: 33 kDa). We believe this band represents the protein product of the unprocessed XBP1 mRNA that is present in the absence of a stress response.

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

    • Function
      Transcription factor essential for hepatocyte growth, the differentiation of plasma cells, the immunoglobulin secretion, and the unfolded protein response (UPR). Acts during endoplasmic reticulum stress (ER) by activating unfolded protein response (UPR) target genes via direct binding to the UPR element (UPRE). Binds DNA preferably to the CRE-like element 5'-GATGACGTG[TG]N(3)[AT]T-3', and also to some TPA response elements (TRE). Binds to the HLA DR-alpha promoter. Binds to the Tax-responsive element (TRE) of HTLV-I.
    • Involvement in disease
      Genetic variations in XBP1 could be associated with susceptibility to major affective disorder type 7 (MAFD7) [MIM:612371]. Major affective disorders represent a class of mental disorders characterized by a disturbance in mood as their predominant feature.
    • Sequence similarities
      Belongs to the bZIP family.
      Contains 1 bZIP domain.
