Rag A CRISPR/Cas9 KO Plasmid (m): sc-427054
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Rag A 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 Rag A 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
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Rag A Antibody (D-1): sc-518209

Overview
Rraga encodes Rag A, a small Ras-related GTPase that functions with RagB/C/D and the Ragulator complex to recruit and regulate mTORC1 at the lysosomal membrane in response to amino acids and nutrient availability. Through nucleotide-dependent heterodimerization, Rag A helps couple cellular nutrient sensing to downstream control of protein synthesis, autophagy, and metabolic reprogramming via the mTOR pathway. Perturbation of Rag GTPase signaling is linked to altered growth control, stress responses, and immune cell activation programs, making Rraga a useful entry point for studying nutrient-dependent signaling networks. In mouse systems, Rraga disruption can illuminate how lysosome-centered signaling integrates with transcriptional and translational regulation in physiology and disease-relevant models.
Rag A CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Rraga gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Rraga 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 Rraga 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 Rag A protein expression.
This CRISPR knockout system enables efficient generation of Rraga-deficient cell models for investigation of Rag A signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

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