RGS4 CRISPR/Cas9 KO Plasmid (h): sc-418013
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- RGS4 CRISPR/Cas9 Knockout (KO) Plasmid (h) 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 RGS4 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: RGS4 Antibody (H-12): sc-398348

Overview
RGS4 encodes Regulator of G protein Signaling 4, a GTPase-activating protein that accelerates termination of GPCR-driven signaling by promoting Gα subunit GTP hydrolysis. By constraining downstream second-messenger pathways such as cAMP/PKA and PLCβ/Ca2+ signaling, RGS4 shapes receptor desensitization, neuronal excitability, and stimulus-dependent transcriptional outputs. It is expressed in multiple tissues with prominent roles in the nervous system and has been linked to modulation of synaptic signaling and neurodevelopmental processes. Altered RGS4 expression and signaling balance have been associated with neuropsychiatric and cognitive phenotypes, making it relevant for mechanistic studies of GPCR pathway regulation.
RGS4 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the RGS4 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the RGS4 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 RGS4 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 RGS4 protein expression.
This CRISPR knockout system enables efficient generation of RGS4-deficient cell models for investigation of RGS4 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by RGS4 CRISPR/Cas9 KO Plasmid (h) and RGS4 CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the RGS4 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by RGS4 HDR Plasmid (h) and RGS4 HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by RGS4 homology arms to support homology-directed repair at defined RGS4 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
