LBP-9 CRISPR Activation Plasmid (h) | sc-404224-ACT | 20 µg | $397.00 |
TFCP2L1 encodes the transcription factor LBP-9, a CP2 family DNA-binding protein that regulates gene expression programs linked to cell identity, epithelial differentiation, and transcriptional control in development. LBP-9 has been implicated in maintaining stem-like states and coordinating signaling-responsive transcription, intersecting with pathways that influence proliferation and lineage commitment. Dysregulated TFCP2L1 activity and altered downstream transcriptional networks have been associated with oncogenic phenotypes and aberrant differentiation in multiple tissue contexts. As a nuclear regulator, LBP-9 provides a useful entry point for studying chromatin-dependent control of gene networks relevant to transformation and cellular plasticity.
LBP-9 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous TFCP2L1 expression without altering the underlying DNA sequence.
LBP-9 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the TFCP2L1 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 TFCP2L1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous LBP-9 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native TFCP2L1 locus and enabling the study of LBP-9-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of LBP-9 pathway restoration in tumor cells with silenced or reduced TFCP2L1 expression.
