Anti-XBP1s Antibody, clone 143F (active form)

XBP-1, also known as X-box-binding protein 1 or Tax-responsive element-binding protein 5, and encoded by the gene XBP1/TREB5/XBP2, is a transcription factor essential for hepatocyte growth, the differentiation of plasma cells, immunoglobulin secretion, and the unfolded protein response (UPR). XBP-1 also acts during endoplasmic reticulum stress (ER) by activating unfolded protein response (UPR) target genes via direct binding to the UPR element (UPRE). XBP-1 binds DNA preferentially at CRE-like elements but also to some TPA response elements (TRE). XBP-1 is expressed in the nucleus. Defects in XBP-1 may be associated with Major affective disorder 7 (MAFD7) a major psychiatric disorder that is characterized by severe mood swings, with fluctuation between two abnormal mood states (manic or major depressive episode). Mania is accompanied by symptoms of euphoria, irritability, or excitation, whereas depression is associated with low mood and decreased motivation and energy.
