The ADCK1 Knockout HAP1 Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout population designed to disrupt the ADCK1 gene in HAP1 cells. This heterogeneous cell pool provides a loss-of-function model for functional studies, bypassing the need for clonal isolation. It is suitable for pooled genetic screens, population-level biochemical assays, and mitochondrial phenotyping, offering a robust platform to investigate ADCK1-dependent processes and coenzyme Q biosynthesis.
HAP1 cells originate from KBM-7 chronic myeloid leukemia cells and are near-haploid, adherent, and fibroblast-like. The haploid genome simplifies CRISPR-based knockout studies as single-allele disruption often yields a null phenotype, making them ideal for functional genomics and genetic screens. HAP1 cells are extensively employed in drug-target discovery and mitochondrial biology due to their stable growth and reproducible metabolic responses.
ADCK1 (COQ8A) encodes an atypical kinase that phosphorylates key coenzyme Q biosynthesis enzymes, including COQ3, COQ5, and COQ7, and functionally interacts with COQ9 to promote complex assembly. This activity is critical for maintaining coenzyme Q levels, which are essential for electron transport chain operation and oxidative phosphorylation. Upstream, ADCK1 is regulated by the mitochondrial unfolded protein response and the transcriptional coactivator PGC-1??, linking mitochondrial stress signals to bioenergetic regulation.
In HAP1 cells, ADCK1 disruption is expected to impair coenzyme Q synthesis, resulting in defective mitochondrial respiration and increased susceptibility to oxidative stress. This phenotype models primary coenzyme Q10 deficiency and related mitochondrial disorders such as cerebellar ataxia. The near-haploid background amplifies these metabolic defects, creating a sensitive system for mechanistic studies and pharmacological rescue experiments.
The cells are applicable for western blotting of ADCK1 and COQ proteins, coenzyme Q quantification by LC-MS, and mitochondrial oxygen consumption measurements using Seahorse or Oroboros instruments. They also support cell viability assays under oxidative stress and haploid genetic interaction mapping. This ADCK1 knockout HAP1 polyclonal population is a potent tool for drug screening targeting mitochondrial metabolism and for functional genomics of mitochondrial diseases.
