KDEL receptor 3 CRISPR/Cas9 KO Plasmid (m): sc-430617
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- KDEL receptor 3 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 KDEL receptor 3 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
Kdelr3 encodes KDEL receptor 3, a Golgi-resident retrieval receptor that recognizes the C-terminal KDEL motif on escaped ER luminal chaperones and returns them from the Golgi to the endoplasmic reticulum via COPI-dependent retrograde trafficking. By maintaining ER proteostasis and calcium homeostasis, KDELR3 influences unfolded protein response signaling, secretory pathway fidelity, and stress-adaptive remodeling of the early secretory compartment. Perturbation of KDEL receptor–mediated retrieval can alter glycoprotein maturation and ER stress sensitivity, processes frequently leveraged in studies of neurodegeneration, metabolic stress, and tumor cell secretory demands. In mouse systems, Kdelr3 provides a tractable node for dissecting how ER–Golgi transport interfaces with proteostasis networks and cell-state transitions.
KDEL receptor 3 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Kdelr3 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Kdelr3 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 Kdelr3 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 KDEL receptor 3 protein expression.
This CRISPR knockout system enables efficient generation of Kdelr3-deficient cell models for investigation of KDEL receptor 3 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by KDEL receptor 3 CRISPR/Cas9 KO Plasmid (m) and KDEL receptor 3 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Kdelr3 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by KDEL receptor 3 HDR Plasmid (m) and KDEL receptor 3 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Kdelr3 homology arms to support homology-directed repair at defined Kdelr3 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
