PP2B-Aβ CRISPR/Cas9 KO Plasmid (m): sc-422384
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- PP2B-Aβ 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 PP2B-Aβ 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: PP2B-Aβ Antibody (A-11): sc-365612

Overview
Ppp3cb encodes the mouse catalytic subunit beta of calcineurin (PP2B-Aβ), a Ca2+/calmodulin-dependent serine/threonine phosphatase that converts calcium signals into phosphorylation-state changes across multiple substrates. PP2B-Aβ is a central node in calcium-dependent signaling, prominently regulating NFAT family transcription factors and shaping programs linked to neuronal excitability, synaptic plasticity, and activity-dependent gene expression. Through coordinated dephosphorylation events, calcineurin influences cytoskeletal remodeling, vesicle trafficking, and stress-responsive signaling cascades. Dysregulated calcineurin activity and PPP3CB-associated signaling have been implicated in neurodevelopmental and neuropsychiatric phenotypes and in broader contexts where aberrant calcium signaling contributes to disease-relevant cellular states.
PP2B-Aβ CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Ppp3cb gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Ppp3cb 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 Ppp3cb 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 PP2B-Aβ protein expression.
This CRISPR knockout system enables efficient generation of Ppp3cb-deficient cell models for investigation of PP2B-Aβ signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by PP2B-Aβ CRISPR/Cas9 KO Plasmid (m) and PP2B-Aβ CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Ppp3cb locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by PP2B-Aβ HDR Plasmid (m) and PP2B-Aβ HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Ppp3cb homology arms to support homology-directed repair at defined Ppp3cb target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
