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. -

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-XBP1 antibody (ab37152)
Immunohistochemistry of mouse testis cells labeling XBP1 with Anti-XBP1 antibody (ab37152) at 2μg/ml. Tissue was fixed with formaldehyde and blocked with 10% serum for 1 h at RT; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4oC. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin.

Tissue was fixed with formaldehyde and a heat mediated antigen retrieval step was performed using Citrate-EDTA antigen retrieval buffer and microwave. Heating was performed in the microwave 3 minutes on high until boiling, 6 minutes on 20% power. Samples were then blocked for 15 minutes at 27°C followed by incubation with the primary antibody at a 1/100 dilution for 12 hours at 4°C. An undiluted HRP-conjugated rat polyclonal was used as the secondary antibody. -
