ABCF3 Knockout HeLa Polyclonal Cells are a CRISPR/Cas9-edited polyclonal HeLa cell population with targeted disruption of the ABCF3 gene. This loss-of-function model is designed for functional genomics studies. As a polyclonal pool, it contains a heterogeneous mix of edited alleles, enabling robust analysis of gene knockout effects at the population level. This product is suitable for investigating the role of ABCF3 in translation regulation and cancer biology.
The host cell line, HeLa, is an immortalized epithelial cell line derived from a cervical adenocarcinoma and is HPV18-positive, exhibiting adherent growth. It has been extensively used in biomedical research due to its robust proliferation and well-characterized molecular landscape, making it a reliable platform for CRISPR-mediated gene knockout studies. Its epithelial origin and cancer background provide a relevant context for probing ABCF3 function in carcinoma cells.
ABCF3 encodes a cytosolic ATP-binding cassette (ABC) ATPase that uniquely lacks transmembrane domains, distinguishing it from typical ABC transporters and implying a role in non-transport processes such as translation initiation, ribosome biogenesis, or cellular stress responses. Current evidence suggests that ABCF3 interacts with ribosomal proteins and translation initiation factors, notably EIF2 and EIF3, and may function downstream of mTOR signaling, a central regulator of protein synthesis. It is related to ABCF1 and ABCF2, which also associate with the ribosome. Although its precise mechanism remains unclear, ABCF3 is hypothesized to modulate translation efficiency or ribosome assembly, potentially under the control of translation demand or stress signals.
In the HeLa cell context, which is characterized by high translational output and altered signaling due to HPV18 E6/E7 oncoproteins, disruption of ABCF3 offers a means to dissect its contributions to ribosome function and translation control. The polyclonal cell population ensures that the observed phenotypes are not biased by clonal variation, providing a more representative loss-of-function model. Given the association of ABCF family members with drug resistance and cancer cell proliferation, this knockout model is particularly relevant for investigating how ABCF3 influences proliferative capacity and chemosensitivity in cervical adenocarcinoma cells.
This product supports a wide range of applications, including Western blotting and RT-qPCR for knockout validation, ribosome profiling and polysome fractionation to monitor translation dynamics, RNA-seq for transcriptome-wide analysis, and co-immunoprecipitation to identify protein interactions. Functional studies can assess cell proliferation and drug sensitivity, placing ABCF3 within cancer biology and translational regulation research.
