The HIVEP1 Knockout Jurkat Polyclonal Cells offer a CRISPR/Cas9-mediated loss?of?function model in a polyclonal population of Jurkat T lymphocytes. This product is generated by disrupting the HIVEP1 gene throughout a pool of cells, providing a heterogeneous knockout background that mirrors population-level gene function studies without clonal artifacts. The polyclonal format is particularly suited for experiments requiring broad representation of editing outcomes, enabling robust assessment of HIVEP1-dependent phenotypes in T cell biology.
The host Jurkat cell line is an immortalized T lymphocyte line originally derived from a patient with acute T cell leukemia. It serves as a widely accepted model system for studying T cell receptor (TCR) signaling, cytokine production, apoptosis, and leukemogenesis. Jurkat cells are highly responsive to stimuli such as phorbol esters and ionomycin, leading to robust activation of NF???B and AP?1 pathways. Their genetic tractability and well?characterized signaling networks make them an ideal platform for gene knockout studies aimed at dissecting molecular mechanisms underlying immune function and malignancy.
HIVEP1 (human immunodeficiency virus type I enhancer binding protein 1) is a zinc?finger transcription factor that binds ??B enhancer motifs. It interacts with NF???B subunits p50 (NFKB1) and p65 (RELA), along with coactivators EP300 and CREBBP. Activated by upstream signals such as TNF???, IL?1??, and TCR engagement, the IKK complex (IKBKB, CHUK, IKBKG) stimulates NF???B, which induces HIVEP1 expression. This factor modulates transcription of targets including IL?2, IL2RA, BCL2, MYC, MMP9, and the HIV?1 LTR, thereby governing immune responses, cell survival, and proliferation. Disruption of HIVEP1 alters NF???B?mediated transcriptional programs.
In Jurkat T cells, HIVEP1 integrates extracellular signals with gene expression programs governing activation and homeostasis. TCR stimulation triggers NF???B?dependent recruitment of HIVEP1 to regulatory regions, fine?tuning cytokines and survival factors. Knockout of HIVEP1 in these polyclonal cells provides a model to investigate altered IL?2 production, apoptotic thresholds via BCL2, and proliferative capacity through MYC. This system is valuable for exploring HIVEP1 contributions to leukemic growth and for testing NF???B pathway inhibitors.
These polyclonal knockout cells are suited for T cell receptor signaling analysis, HIV?1 LTR transcriptional control studies, and NF???B modulator screening. Techniques include Western blotting, RT?qPCR, NF???B luciferase reporter assays, flow cytometry for CD69 and CD25, annexin?V apoptosis detection, ChIP?qPCR for ??B site occupancy, and co?immunoprecipitation for protein interactions. These assays enable dissection of HIVEP1 interactions with NF???B components and downstream networks. For additional technical information or customized services, please contact Ascent Research.
