RPA40 CRISPR/Cas9 KO Plasmid (h) | sc-404594 | 20 µg | $397.00 |
POLR1C encodes RPA40, a shared subunit of RNA polymerase I and RNA polymerase III that supports assembly and stability of these transcription complexes. Through its roles in rRNA synthesis by Pol I and transcription of tRNAs and other small noncoding RNAs by Pol III, RPA40 contributes to ribosome biogenesis, proteostasis, and cell growth control. Disruption of POLR1C-linked transcriptional output can alter nucleolar function and cellular stress responses, connecting this factor to pathways that influence proliferation and differentiation. Variants in POLR1C have been associated with inherited disorders affecting myelin and craniofacial development, underscoring the importance of Pol I/III integrity in human biology.
RPA40 CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the POLR1C gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the POLR1C 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 POLR1C 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 RPA40 protein expression.
This CRISPR knockout system enables efficient generation of POLR1C-deficient cell models for investigation of RPA40 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.
