The IP6K1 Knockout Jurkat Polyclonal Cells represent a CRISPR/Cas9-edited polyclonal knockout cell population in which the IP6K1 gene has been disrupted. This product provides a pooled population of Jurkat cells carrying heterogeneous loss-of-function mutations, enabling the study of inositol pyrophosphate signaling without clonal selection artifacts. The polyclonal format is well-suited for bulk biochemical, pharmacological, and functional assays where a mixed genetic background reflects population-level responses.
The Jurkat host cell line is a widely used human T lymphocyte model originally derived from acute T cell leukemia. As a suspension cell line, it is amenable to high-throughput handling and has been instrumental in dissecting T cell receptor (TCR) signaling, apoptosis, and cytokine responses. Its robust growth and well-characterized signaling networks make it an ideal platform for interrogating the role of metabolic and stress-related enzymes in immune cell biology.
IP6K1 (inositol hexakisphosphate kinase 1) catalyzes the conversion of inositol hexakisphosphate (IP6) to the inositol pyrophosphate 5-IP7. This reaction integrates insulin and growth factor signals, placing IP6K1 at the nexus of PI3K/Akt and mTOR pathways. Upon activation by upstream regulators such as insulin and IGF-1, IP6K1 generates 5-IP7, which directly modulates Akt phosphorylation by PDK1 and mTOR, and interacts with DNA repair complexes including DNA-PKcs and Ku70/Ku80. In parallel, IP6K1 influences p53-dependent apoptosis and DNA repair through 5-IP7-mediated regulation of the p53?CDNA-PK axis.
In Jurkat T cells, disruption of IP6K1 ablates 5-IP7 production, leading to altered TCR signaling dynamics, impaired Akt/mTOR activation, and reduced cytokine outputs such as IL-2. Consequently, these polyclonal knockout cells exhibit defects in survival and apoptosis regulation, mirroring phenotypes observed in metabolic and cancer models. The model thus recapitulates key aspects of IP6K1 biology in a leukemic T cell context, providing a physiologically relevant system to dissect inositol pyrophosphate-dependent mechanisms in lymphocyte function and transformation.
Researchers can employ this knockout model to explore the role of inositol pyrophosphates in T cell signal transduction, metabolic sensing, and programmed cell death. Typical applications include Western blot analysis of phospho-Akt and IP6K1 levels, RT-qPCR confirmation of gene disruption, HPLC-based intracellular inositol phosphate profiling, flow cytometric assessment of apoptosis using Annexin V/PI staining, and IL-2 secretion assays to evaluate functional consequences. This tool also supports inhibitor screening campaigns targeting the IP6K1?CAkt?CmTOR axis. For additional information, please contact Ascent Research.
