BI-1 CRISPR Activation Plasmid (h) | sc-404349-ACT | 20 µg | $397.00 |
TMBIM6 encodes BI-1, an endoplasmic reticulum membrane protein that suppresses apoptosis by modulating ER calcium homeostasis and attenuating ER stress signaling. BI-1 influences unfolded protein response pathways, including PERK–eIF2α and IRE1-mediated signaling, and can shape oxidative stress and mitochondrial crosstalk that determines cell survival under proteotoxic conditions. Through these functions, TMBIM6 is frequently studied in the context of cellular adaptation to chronic stress, with reported associations to tumor cell survival, neurodegeneration-related stress vulnerability, and inflammatory responses driven by disrupted proteostasis.
BI-1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous TMBIM6 expression without altering the underlying DNA sequence.
BI-1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the TMBIM6 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 TMBIM6 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous BI-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native TMBIM6 locus and enabling the study of BI-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of BI-1 pathway restoration in tumor cells with silenced or reduced TMBIM6 expression.
