Human TGIF2 (TG-interacting factor 2) encodes a TALE-class homeobox transcriptional regulator that modulates gene expression programs controlling cell fate decisions, proliferation, and differentiation. TGIF2 functions primarily as a transcriptional corepressor by partnering with SMAD proteins and recruiting corepressor complexes, thereby shaping TGF-β/SMAD signaling outputs and broader developmental transcriptional networks. Through these interactions, TGIF2 influences epithelial–mesenchymal transition-related programs, lineage specification, and context-dependent growth control. Dysregulated TGIF2 expression or activity has been associated with altered transcriptional states observed in developmental disorders and cancers, making it relevant for mechanistic studies of signaling-dependent gene regulation.
TGIF2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous TGIF2 expression without altering the underlying DNA sequence.
TGIF2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the TGIF2 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 TGIF2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous TGIF2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native TGIF2 locus and enabling the study of TGIF2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of TGIF2 pathway restoration in tumor cells with silenced or reduced TGIF2 expression.
