DMKN Knockout HEK293T Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout population harboring targeted disruption of the DMKN gene, providing a loss?of?function model for studying DMKN biology. The product comprises a heterogeneous pool of edited HEK293T cells, avoiding clonal biases while achieving robust gene disruption. This polyclonal format is suitable for population?based assays and reduces artifacts associated with single?cell cloning.
The host cell line, HEK293T, is an SV40 large T?antigen?transformed human embryonic kidney epithelial cell line, widely used for its high transfection efficiency, protein expression, and viral production capacity. These adherent cells retain epithelial characteristics and provide a well?characterized, easily cultured platform for investigating gene function in an epithelial context.
DMKN encodes dermokine, a secreted protein critical for late epidermal differentiation, acting through regulation of extracellular matrix (ECM) organization and cell adhesion. Its expression is activated by calcium influx, p63, AP?1 transcription factors, and Notch signaling. DMKN interacts with ECM proteins collagen IV, laminin?5, and fibronectin, and downstream it modulates integrins, collagens, and laminins. Within the epidermal differentiation network, DMKN functions alongside p63, involucrin, and keratin 10 to promote barrier integrity. Knockout of DMKN is thus predicted to disrupt ECM?cell adhesive interactions and differentiation programs.
Although HEK293T cells do not undergo terminal epidermal differentiation, they serve as a simplified epithelial model for dissecting DMKN??s core functions. In this background, DMKN knockout enables analysis of its roles in ECM organization and adhesion without interference from other skin?specific pathways. This system can reveal how DMKN coordinates integrin signaling and matrix deposition, providing mechanistic insights relevant to epithelial barrier disorders such as psoriasis and atopic dermatitis.
Researchers can employ DMKN Knockout HEK293T Polyclonal Cells to investigate DMKN function via Western blotting and RT?qPCR for differentiation markers, immunofluorescence for adhesion proteins, and cell adhesion assays on defined ECM substrates. The polyclonal format is ideal for RNA?seq to identify gene expression changes and for ECM remodeling assays. This knockout model supports diverse functional studies in epithelial biology.
