It encodes a transcription factor that regulates MHC class II genes by binding to a promoter element referred to as an X box. This gene product is a bZIP protein, which was also identified as a cellular transcription factor that binds to an enhancer in the promoter of the T cell leukemia virus type 1 promoter. It may increase expression of viral proteins by acting as the DNA binding partner of a viral transactivator. It has been found that upon accumulation of unfolded proteins in the endoplasmic reticulum (ER), the mRNA of this gene is processed to an active form by an unconventional splicing mechanism that is mediated by the endonuclease inositol-requiring enzyme 1 (IRE1). The resulting loss of 26 nt from the spliced mRNA causes a frame-shift and an isoform XBP1 (S), which is the functionally active transcription factor. The isoform encoded by the unspliced mRNA, XBP1 (U), is constitutively expressed, and thought to function as a negative feedback regulator of XBP1 (S), which shuts off transcription of target genes during the recovery phase of ER stress. A pseudogene of XBP1 has been identified and localized to chromosome 5.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eImmunogen\u003c\/b\u003e: A synthetic peptide corresponding to a sequence at the N-terminus of human XBP1, identical to the related mouse and rat sequences.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eClonality\u003c\/b\u003e: Polyclonal\u003c\/p\u003e\u003cp\u003e\u003cb\u003eContents\u003c\/b\u003e: Each vial contains antibody formulated with stabilizing components, 0.9 mg NaCl, 0.2 mg Na2HPO4, and 0.05 mg NaN3.\u003cbr\u003e\n*This antibody is supplied in a stabilized formulation. \u003cbr\u003e\nCompatibility with conjugation reactions depends on the chemistry of the conjugation method used. \u003cbr\u003e\nFor conjugation methods that are not compatible with the stabilizing components present in this formulation, a carrier-free antibody format is required.\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurification\u003c\/b\u003e: Immunogen affinity purified.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e: Add 0.2ml of distilled water will yield a concentration of 500ug\/ml.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReference\u003c\/b\u003e: 1.
