AGS3 Double Nickase Plasmid (m): sc-426766-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- AGS3 Double Nickase Plasmid (m) consists of a pair of plasmids each encoding a D10A mutated Cas9 nuclease and a target-specific 20 nt guide RNA (gRNA) designed to knockout gene expression with greater specificity than its CRISPR/Cas9 KO counterpart
- Paired gRNA sequences are offset by approximately 20 bp to allow for specific Cas9-mediated double nicking of the genomic DNA, which mimics a DSB
- One plasmid in the pair contains a puromycin-resistance gene for selection; the other plasmid in the pair contains a GFP marker to visually confirm transfection
- AGS3 Double Nickase Plasmid (m) and AGS3 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Gpsm1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: AGS3 Antibody (G-2): sc-271721

Mouse Gpsm1 encodes activator of G-protein signaling 3 (AGS3), a multidomain regulator that binds GDP-loaded Gαi/o subunits via its GoLoco motifs and modulates heterotrimeric G-protein cycling independently of canonical GPCR activation. AGS3 influences second-messenger signaling and receptor trafficking, shaping downstream pathways that control cell polarity, vesicle dynamics, and cytoskeletal organization. In the nervous system, AGS3 is linked to synaptic plasticity and adaptive responses to neuromodulatory cues, while in other tissues it contributes to context-dependent control of proliferative and migratory behaviors. Dysregulated G protein signaling networks involving AGS3 are studied in neurobehavioral phenotypes and signaling rewiring associated with tumor biology, making Gpsm1 a useful target for mechanistic pathway interrogation.
AGS3 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Gpsm1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Gpsm1. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt Gpsm1 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of Gpsm1-disrupted clones.
