Mouse Nipbl encodes NIPBL, a cohesin-loading factor that positions the cohesin complex on chromatin to support sister chromatid cohesion, DNA replication, and chromosome segregation. Beyond mitosis, NIPBL helps organize higher-order genome architecture and regulates developmental transcriptional programs by influencing enhancer–promoter communication. Through these roles it impacts pathways linked to genome stability and cell fate decisions, including responses to replication stress and double-strand break repair. Dysregulated NIPBL function is associated with cohesinopathy-related phenotypes and has been used to model mechanisms underlying neurodevelopmental and growth abnormalities in vivo and in cell-based systems.
NIPBL CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Nipbl expression without altering the underlying DNA sequence.
NIPBL CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Nipbl locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the Nipbl transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous NIPBL expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Nipbl locus and enabling the study of NIPBL-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of NIPBL pathway restoration in tumor cells with silenced or reduced Nipbl expression.
