FIH-1 CRISPR Activation Plasmid (h) | sc-402511-ACT | 20 µg | $397.00 |
HIF1AN encodes factor inhibiting HIF-1 (FIH-1), an Fe(II)/2-oxoglutarate–dependent asparaginyl hydroxylase that attenuates hypoxia-inducible transcription by hydroxylating HIF-1α and limiting coactivator (CBP/p300) recruitment. Through this post-translational control point, FIH-1 integrates oxygen-sensing with metabolic reprogramming, angiogenic signaling, and redox homeostasis within the HIF pathway. FIH-1 also modifies ankyrin repeat–containing proteins, linking oxygen availability to broader transcriptional and signaling networks. Dysregulated HIF signaling and altered HIF1AN activity have been associated with hypoxia-driven phenotypes relevant to cancer biology, ischemia, inflammation, and metabolic disease mechanisms.
FIH-1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous HIF1AN expression without altering the underlying DNA sequence.
FIH-1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the HIF1AN 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 HIF1AN transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous FIH-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native HIF1AN locus and enabling the study of FIH-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of FIH-1 pathway restoration in tumor cells with silenced or reduced HIF1AN expression.
