The KRT10 Knockout HAP1 Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout population disrupting the KRT10 gene. This heterogeneous pool provides a loss-of-function model for keratin 10 studies, capturing diverse editing outcomes for robust population-level analyses. It is suited for researchers exploring intermediate filament dynamics and epidermal differentiation pathways.
HAP1 is a near-haploid human cell line derived from KBM-7 chronic myeloid leukemia cells. It grows adherently with fibroblast-like morphology and retains single copies of most chromosomes, facilitating straightforward genetic analysis. Widely used in CRISPR screens and functional genomics, HAP1’s haploidy reduces redundancy and simplifies interpretation of gene disruption effects.
KRT10 encodes keratin 10, a type I intermediate filament protein that obligately pairs with keratin 1 (KRT1) to form suprabasal filaments in the epidermis. Its expression is activated by TP63, AP-1, Notch, and calcium signaling. KRT10?CKRT1 filaments interact with desmoplakin, plakoglobin, and filaggrin, contributing to desmosome integrity, cell adhesion, and mechanical resilience. Knockout of KRT10 eliminates these filaments, disrupting desmosome stability and impairing terminal differentiation processes central to epidermal barrier function.
In the HAP1 context, KRT10 loss dismantles the inherent intermediate filament network, offering a simplified model to investigate keratin-dependent cellular functions. Although not keratinocytic, HAP1??s near-haploid genome enables clear dissection of cytoskeletal organization, adhesion, migration, and plasticity effects. This system aids in uncovering non-canonical roles of keratins in cancer and identifying synthetic lethal interactions, providing a versatile platform for mechanistic studies.
Key research applications include modeling keratinopathies (epidermolytic hyperkeratosis, keratoderma, bullous ichthyosiform erythroderma), epidermal differentiation, barrier formation, and drug screening. Compatible assays include immunofluorescence of keratin networks, western blotting for KRT10 and differentiation markers, RT-qPCR, and migration/invasion assays. This polyclonal knockout population serves as a functional genomics tool for both basic and translational investigations. For additional information, contact Ascent Research.
