The ANKRD18A Knockout HEK293T Polyclonal Cells are a polyclonal cell population harboring CRISPR/Cas9-mediated disruption of the human ANKRD18A gene. This polyclonal knockout model provides a heterogeneous loss-of-function resource for studying the ankyrin repeat domain-containing protein 18A. By maintaining genetic diversity and avoiding clonal selection, this format is particularly suited for functional assays that benefit from population-level representation.
The parental HEK293T cell line is a human embryonic kidney epithelial line expressing the SV40 large T antigen, derived from HEK293 cells that were originally transformed with sheared adenovirus 5 DNA. This modification enables episomal replication of SV40 origin-containing plasmids and confers high transfection efficiency, making HEK293T a preferred system for recombinant protein expression, lentiviral packaging, and CRISPR applications. Its thoroughly characterized genetics and robust growth support the generation of knockout models for understudied genes like ANKRD18A.
ANKRD18A belongs to the ankyrin repeat domain-containing protein family, which is characterized by tandem ankyrin repeat motifs that frequently mediate specific protein-protein interactions. These domains function as molecular scaffolds, facilitating the assembly of multi-protein complexes and participation in signal transduction networks. Although the precise cellular function of ANKRD18A remains undetermined, its domain organization suggests roles in complex formation and possibly in regulating processes such as transcriptional control or cytoskeletal dynamics. The knockout of ANKRD18A in HEK293T cells is anticipated to disrupt interaction networks dependent on this protein, offering a path to identify binding partners and downstream pathways. No upstream regulators, downstream targets, or interacting factors have been definitively characterized for ANKRD18A, emphasizing the need for functional studies using this model.
Combining the uncharacterized ANKRD18A gene with the biochemically accessible HEK293T host creates a powerful platform for foundational discovery. Researchers can employ this knockout population to assess the impact of ANKRD18A loss on cell proliferation, viability, and morphology using standard assays. Moreover, the polyclonal nature supports unbiased proteomic strategies, such as co-immunoprecipitation or pull-down experiments, to reveal novel interacting proteins, while minimizing artifacts from clonal selection. This model thus enables robust, population-level dissection of ANKRD18A function.
This ANKRD18A knockout polyclonal product is engineered for multiple research applications, including functional characterization of ANKRD18A, exploration of ankyrin repeat-mediated biology, and deployment as a specificity control in CRISPR screens targeting related ankyrin repeat proteins. Representative compatible assays include Western blotting for protein depletion analysis, RT-qPCR for transcript quantification, genomic DNA sequencing for indel validation, co-immunoprecipitation and pull-down for interaction partner identification, immunofluorescence for subcellular localization, and proliferation or viability assays. By providing a stable loss-of-function model in a versatile cell line, this product facilitates detailed mechanistic investigation of ANKRD18A. For technical support, contact Ascent Research.
