The DNAJC15 Knockout HeLa Polyclonal Cells product is a CRISPR/Cas9-edited polyclonal knockout cell population derived from HeLa cells, designed for targeted disruption of the DNAJC15 gene. This polyclonal population provides a heterogeneous loss-of-function model that allows researchers to study gene function in a pooled format, capturing a spectrum of editing outcomes while maintaining experimental robustness.
HeLa cells are an immortalized human cervical adenocarcinoma epithelial cell line harboring integrated HPV18 sequences, which produce viral oncoproteins E6 and E7 that functionally inactivate the tumor suppressors p53 and Rb, respectively. This genetic background drives deregulated cell cycle progression and genomic instability, establishing HeLa as a widely utilized model in cancer biology, protein expression studies, and drug discovery research.
The DNAJC15 gene encodes a mitochondrial matrix co-chaperone that directly interacts with mitochondrial Hsp70 (mtHsp70/HSPA9) and the Tim23 subunit of the TIM23 translocase to facilitate protein import and folding. DNAJC15 functions as a negative regulator of respiratory complex I activity, thereby modulating oxidative phosphorylation, ATP synthesis, and reactive oxygen species (ROS) production. Its expression is controlled by upstream factors including mitochondrial stress signals, the transcription factor NRF1, and promoter methylation. Within the mitochondrial import pathway, DNAJC15 operates alongside representative components such as Tom40, Tim23, Pam18, and Tim44, forming a network that couples protein translocation to matrix chaperone machinery. Disruption of DNAJC15 affects downstream targets including complex I subunits, ATP synthesis, and ROS levels, ultimately influencing intrinsic apoptosis.
In the HeLa cellular context, where p53 and Rb inactivation fosters aberrant metabolic and survival pathways, mitochondrial function is essential for meeting bioenergetic demands and regulating cell death. Targeting DNAJC15 in this background offers a powerful tool to dissect its contributions to mitochondrial protein import, respiratory chain regulation, and metabolic rewiring in cancer cells. The resulting polyclonal knockout population is particularly relevant for investigations into how mitochondrial co-chaperones modulate cancer cell fitness, response to mitochondrial stress, and sensitivity to metabolic perturbations, with implications for mitochondrial disorders and metabolic diseases.
This product supports a wide array of experimental applications, including mitochondrial isolation and co-immunoprecipitation to examine interactions with mtHsp70 and Tim23, western blotting and RT-qPCR for expression profiling, and Seahorse metabolic flux analysis to assess oxygen consumption and ATP production. Additional compatible assays include flow cytometry for mitochondrial membrane potential evaluation, immunofluorescence microscopy for mitochondrial morphology and protein localization, and apoptosis assays to probe cell death pathways. Researchers studying mitochondrial protein import, respiration, cancer metabolism, or stress responses will find this DNAJC15 knockout polyclonal population a valuable tool.
