TSSK 2 CRISPR/Cas9 KO Plasmid (m): sc-423532
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- TSSK 2 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 TSSK 2 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
Mouse Tssk2 encodes testis-specific serine/threonine-protein kinase 2 (TSSK2), a germ cell–enriched kinase implicated in post-meiotic spermatid differentiation and the molecular remodeling events required for sperm maturation. TSSK family kinases are associated with phosphorylation-dependent control of spermiogenesis programs, including chromatin reorganization, cytoskeletal dynamics, and assembly of flagellar structures. Disruption of TSSK signaling has been linked to defects in male fertility and abnormal sperm function in experimental models, making TSSK2 a useful node for studying reproductive biology. As a testis-restricted kinase, TSSK2 also serves as a model for dissecting tissue-specific kinase networks and proteostasis during late-stage germ cell development.
TSSK 2 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Tssk2 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Tssk2 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 Tssk2 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 TSSK 2 protein expression.
This CRISPR knockout system enables efficient generation of Tssk2-deficient cell models for investigation of TSSK 2 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by TSSK 2 CRISPR/Cas9 KO Plasmid (m) and TSSK 2 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Tssk2 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by TSSK 2 HDR Plasmid (m) and TSSK 2 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Tssk2 homology arms to support homology-directed repair at defined Tssk2 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
