The ANKRD40 Knockout Jurkat Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout cell population generated on the Jurkat background, targeting the ANKRD40 gene. This heterogeneous pool of cells carries diverse loss-of-function mutations, providing a robust model to study ANKRD40 function without the constraints of clonal variation. The CRISPR/Cas9 system has been employed to disrupt the gene, enabling researchers to interrogate its biological role in a human T lymphocyte context.
Jurkat cells are an immortalized human T cell line derived from an acute T cell leukemia patient, widely used to investigate T cell receptor (TCR) signaling, activation, and apoptosis. Their well-characterized signaling networks and ease of manipulation make them a gold standard for immunological studies. The Jurkat background facilitates examination of gene function in pathways governing immune responses, cytokine production, and programmed cell death.
ANKRD40 encodes a protein containing ankyrin repeat domains, which are evolutionarily conserved motifs known to mediate protein-protein interactions. Although the precise function of ANKRD40 remains uncharacterized, it is predicted to act as a scaffold or adaptor within signaling complexes. In T cells, scaffold proteins play critical roles in organizing signal transduction cascades downstream of receptors such as the TCR, potentially influencing kinase activation, second messenger production, and transcriptional outcomes. Disruption of ANKRD40 may therefore alter the assembly or stability of multiprotein complexes, perturbing downstream signaling events.
In the Jurkat cell model, knockout of ANKRD40 provides a valuable system to investigate its involvement in T cell biology. By comparing ANKRD40-deficient and wild-type Jurkat cells, researchers can assess changes in TCR-induced activation, proliferation, and apoptosis. This loss-of-function approach may reveal whether ANKRD40 contributes to the regulation of pathways governing immune synapse formation, NFAT/NF-??B transcription, or mitochondrial apoptosis, offering insights into its cellular roles.
Key research applications include verification of knockout via Western blotting and RT-qPCR, mapping protein interaction networks through co-immunoprecipitation, and functional phenotyping using flow cytometry to measure activation markers such as CD69 or CD25 upon stimulation. Apoptosis assays can evaluate sensitivity to death receptor or intrinsic apoptotic stimuli. This product is suited for researchers in immunology, cell signaling, and functional genomics seeking to elucidate the roles of uncharacterized scaffold proteins.
