The KANK2 Knockout HAP1 Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout cell population derived from the HAP1 human haploid cell line, featuring targeted disruption of the KANK2 gene. This loss-of-function model employs CRISPR/Cas9-mediated gene disruption to generate a heterogeneous pool of cells bearing diverse loss-of-function alleles, providing a versatile tool for rigorous functional genomics experiments without the need for clonal isolation.
HAP1 originates from the KBM-7 chronic myeloid leukemia line and exhibits a near-haploid karyotype, which greatly simplifies knockout generation by requiring only single-allele targeting. These cells display an adherent, fibroblast-like morphology and are of male origin, and they have become a standard host for genetic screening and functional studies. In this polyclonal knockout population, KANK2 disruption in the haploid background eliminates gene dosage complications, enabling straightforward genotype-phenotype correlations.
KANK2 encodes a scaffold protein that bridges integrin-talin complexes to the actin cytoskeleton through interactions with Liprin-??1 and LL5??, thereby controlling focal adhesion dynamics and cell migration. Upstream regulators include integrins, talin, mechanical stress, Src family kinases, and FAK, while downstream it modulates RhoA and Rac1 GTPases, mDia, cortactin, and negatively regulates YAP/TAZ by promoting cytoplasmic retention. This positions KANK2 at the intersection of integrin signaling and Hippo pathway mechanotransduction, with a representative molecular chain of integrin ??1?Ctalin?CKANK2?CLiprin-??1?CLL5?? regulating YAP/TAZ subcellular localization and RhoA?CROCK activity.
Within the HAP1 background, KANK2 knockout permits dissection of adhesion and migration processes uncoupled from other talin-binding proteins, leveraging the near-haploid genome for unambiguous loss-of-function analysis. The polyclonal makeup provides a spectrum of disruptive mutations, making it especially useful for pooled screening applications and for assessing overall phenotypic consequences of KANK2 ablation without single-clone bias. This system is particularly valuable for investigating focal adhesion maturation and mechanosensitive YAP/TAZ regulation in a genetically tractable model.
These cells support a variety of experimental approaches, including Western blotting for KANK2, immunofluorescence analysis of focal adhesion markers such as vinculin and paxillin, wound healing and Transwell migration assays, and Rho GTPase activation measurements. Co-immunoprecipitation can be performed to study KANK2 interactions with talin and integrin ??1, and YAP/TAZ subcellular localization can be examined under different mechanical conditions. The model facilitates research into nephrotic syndrome, cancer metastasis, focal segmental glomerulosclerosis, and drug response profiling.
