Gene: XBP1
Official Full Name: X-box binding protein 1provided by HGNC
Gene Summary: This gene 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. [provided by RefSeq, Jul 2008]

XBP1 Gene Knockout Cell Lines represent a revolutionary tool for studying the role of the XBP1 gene in cellular stress responses and adaptive mechanisms, particularly under endoplasmic reticulum (ER) stress conditions. These genetically engineered cell lines are created using CRISPR-Cas9 technology to effectively disrupt the XBP1 gene, thereby allowing researchers to assess the functional consequences of XBP1 deficiency on various cellular processes including apoptosis, metabolism, and immune response.
The core function of XBP1 pertains to its role as a transcription factor that is integral to the unfolded protein response (UPR). Under conditions of ER stress, XBP1 is spliced to its active form, which promotes the transcription of genes aimed at restoring ER homeostasis. By utilizing XBP1 Gene Knockout Cell Lines, researchers can elucidate the specific pathways regulated by XBP1 and investigate how its absence influences cellular resilience, drug response, and disease progression.
This biological product is critically important in both research and clinical settings, particularly in the fields of cancer research, immunology, and neurodegenerative diseases. Understanding the function of XBP1 can advance therapeutic strategies aimed at targeting diseases characterized by ER stress, like certain cancers and metabolic disorders.
What sets XBP1 Gene Knockout Cell Lines apart from traditional methods is the precision and efficiency offered by CRISPR-Cas9 technology. Researchers benefit from highly reproducible results that allow for detailed manipulation of gene function in various model systems. The ability to create these knockout cell lines with minimal off-target effects enhances the specificity and credibility of experimental data, thus bolstering scientific conclusions.
For researchers and clinicians looking to deepen their understanding of cellular stress responses and their implications in disease, XBP1 Gene Knockout Cell Lines provide an invaluable resource.
