DUSP22 CRISPR/Cas9 KO Plasmid (m): sc-430587
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- DUSP22 CRISPR/Cas9 Knockout (KO) Plasmid (m) is a pool of plasmids, each encoding Cas9 nuclease and a target-specific 20 nt guide RNA (gRNA) designed for maximum knockout efficiency using sequences derived from the GeCKO v2 library
- gRNA sequences direct Cas9 to induce site-specific double-strand breaks (DSBs) in the DUSP22 genomic locus, resulting in gene knockout through non-homologous end joining (NHEJ)
- The puromycin resistance and RFP genes are flanked by LoxP sites, enabling removal of selection markers via Cre recombinase (Cre Vector: sc-418923) after establishing stable knockout cell lines

Overview
Dusp22 encodes dual specificity phosphatase 22 (DUSP22), an atypical MAPK phosphatase that modulates phosphorylation-dependent signaling by dephosphorylating serine/threonine and tyrosine residues on select substrates. In mouse immune and non-immune cells, DUSP22 has been linked to regulation of MAPK pathway dynamics, including stress- and mitogen-responsive signaling nodes that shape transcriptional outputs such as cytokine programs, activation thresholds, and apoptosis. Through its impact on kinase–phosphatase balance, DUSP22 influences cell proliferation and differentiation decisions that are frequently perturbed in inflammatory conditions and cancer biology. Altered DUSP22 signaling has been associated with immune dysregulation and oncogenic pathway rewiring, making it relevant for mechanistic studies of signaling-dependent phenotypes.
DUSP22 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Dusp22 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Dusp22 together with the Streptococcus pyogenes Cas9 nuclease. The plasmids also encode GFP, allowing fluorescent identification and enrichment of successfully transfected cells by fluorescence microscopy or flow cytometry.
The multi-guide design increases the likelihood of generating insertions or deletions (indels) that disrupt the Dusp22 open reading frame following Cas9-mediated double-strand break formation. DNA breaks introduced by the CRISPR/Cas9 system are repaired through endogenous non-homologous end joining (NHEJ) pathways, frequently resulting in frameshift mutations that abolish DUSP22 protein expression.
This CRISPR knockout system enables efficient generation of Dusp22-deficient cell models for investigation of DUSP22 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by DUSP22 CRISPR/Cas9 KO Plasmid (m) and DUSP22 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Dusp22 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by DUSP22 HDR Plasmid (m) and DUSP22 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Dusp22 homology arms to support homology-directed repair at defined Dusp22 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
