GBX2 CRISPR Activation Plasmid (h) | sc-404749-ACT | 20 µg | $397.00 |
GBX2 (gastrulation brain homeobox 2) encodes a homeobox transcription factor that regulates regional patterning and cell fate decisions during early embryogenesis and neurodevelopment. In human cells, GBX2 coordinates transcriptional programs involved in anterior–posterior neural specification and interacts with developmental signaling networks, including WNT/β-catenin, FGF, and retinoic acid–responsive pathways. Dysregulated GBX2 expression has been reported in multiple disease contexts, where altered developmental transcriptional control can contribute to aberrant proliferation, differentiation blockade, and lineage switching. As a nuclear DNA-binding regulator, GBX2 is commonly studied for its role in transcriptional circuitry, chromatin-state modulation, and developmental gene network rewiring in cancer and stem cell models.
GBX2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous GBX2 expression without altering the underlying DNA sequence.
GBX2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the GBX2 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 GBX2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous GBX2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native GBX2 locus and enabling the study of GBX2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of GBX2 pathway restoration in tumor cells with silenced or reduced GBX2 expression.
