CRM1 CRISPR/Cas9 KO Plasmid (h2) | sc-400348-KO-2 | 20 µg | $397.00 |
XPO1 encodes the nuclear export receptor CRM1, a karyopherin-β family protein that recognizes leucine-rich nuclear export signals and mediates RanGTP-dependent transport of proteins and select RNAs from the nucleus to the cytoplasm. By controlling nucleocytoplasmic trafficking, CRM1 regulates cell-cycle progression, stress responses, and transcriptional programs through localization of cargos such as tumor suppressors, transcription factors, and ribonucleoprotein complexes. CRM1 function integrates with the Ran GTPase cycle and nuclear pore complex dynamics to maintain compartmentalized signaling and proteostasis. Dysregulated XPO1/CRM1 activity and altered cargo distribution are frequently studied in cancer biology, antiviral responses, and neurodegenerative mechanisms where nuclear–cytoplasmic transport is perturbed.
CRM1 CRISPR/Cas9 KO Plasmid (h2) is a pool of plasmids designed for targeted disruption of the XPO1 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the XPO1 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 XPO1 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 CRM1 protein expression.
This CRISPR knockout system enables efficient generation of XPO1-deficient cell models for investigation of CRM1 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.
