OIP5 CRISPR Activation Plasmid (h) | sc-409486-ACT | 20 µg | $397.00 |
OIP5 (Opa-interacting protein 5) is a conserved cell cycle regulator enriched at centromeres and tightly linked to chromosome segregation and mitotic progression. It contributes to kinetochore/centromere function and supports proper spindle assembly, aligning OIP5 activity with core mitotic control networks that safeguard genomic stability. Dysregulated OIP5 expression has been associated with proliferative states and is frequently studied in the context of aneuploidy, chromosomal instability, and cancer biology. As a proliferation-linked factor, OIP5 is also used as a molecular entry point to investigate cell cycle–dependent transcriptional programs and mitotic checkpoint regulation in human cells.
OIP5 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous OIP5 expression without altering the underlying DNA sequence.
OIP5 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the OIP5 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 OIP5 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous OIP5 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native OIP5 locus and enabling the study of OIP5-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of OIP5 pathway restoration in tumor cells with silenced or reduced OIP5 expression.
