Dexras2 CRISPR/Cas9 KO Plasmid (r): sc-437366
- Target species: rat
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Dexras2 CRISPR/Cas9 Knockout (KO) Plasmid (r) 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 Dexras2 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
Dexras2 (RASD2) is a small Ras-related GTP-binding protein enriched in neural tissues that functions as a signaling switch downstream of G protein–coupled receptors and neuronal nitric oxide synthase pathways. It helps couple receptor stimulation to changes in cyclic nucleotide signaling, calcium-dependent responses, and synaptic plasticity through modulation of adenylyl cyclase and downstream kinase cascades. In rat systems, Dexras2 has been used to interrogate mechanisms controlling circadian and dopamine-linked neuronal signaling, with relevance to neurobehavioral phenotypes and stress-responsive circuitry. Dysregulation of RAS-family signaling nodes like Dexras2 is broadly informative for studying aberrant signal transduction, neuronal excitability, and pathway cross-talk implicated in CNS dysfunction.
Dexras2 CRISPR/Cas9 KO Plasmid (r) is a pool of plasmids designed for targeted disruption of the gene in rat cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the 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 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 Dexras2 protein expression.
This CRISPR knockout system enables efficient generation of -deficient cell models for investigation of Dexras2 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by Dexras2 CRISPR/Cas9 KO Plasmid (r) and Dexras2 CRISPR/Cas9 KO Plasmid (r2) target distinct sites within the locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by Dexras2 HDR Plasmid (r) and Dexras2 HDR Plasmid (r2) contain a puromycin resistance cassette and an RFP reporter flanked by homology arms to support homology-directed repair at defined target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
