GRK 1 CRISPR/Cas9 KO Plasmid (h): sc-406525
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- GRK 1 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 GRK 1 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: GRK 1 Antibody (D11): sc-56910

Overview
GRK1 encodes G protein–coupled receptor kinase 1 (rhodopsin kinase), a serine/threonine kinase that phosphorylates light-activated rhodopsin to promote arrestin binding and timely termination of phototransduction in rod photoreceptors. This activity is central to GPCR desensitization and signal adaptation in the retina, coordinating recovery kinetics and limiting prolonged downstream signaling. Disruption of GRK1 function is associated with inherited retinal disorders, including congenital stationary night blindness, reflecting impaired deactivation of rod signaling. GRK1 is therefore widely studied in pathways governing GPCR regulation, visual cycle–linked stress responses, and photoreceptor homeostasis.
GRK 1 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the GRK1 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the GRK1 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 GRK1 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 GRK 1 protein expression.
This CRISPR knockout system enables efficient generation of GRK1-deficient cell models for investigation of GRK 1 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by GRK 1 CRISPR/Cas9 KO Plasmid (h) and GRK 1 CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the GRK1 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by GRK 1 HDR Plasmid (h) and GRK 1 HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by GRK1 homology arms to support homology-directed repair at defined GRK1 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
