Mouse Ido2 encodes indoleamine 2,3-dioxygenase 2 (INDOL1), a heme-dependent enzyme that catalyzes oxidative cleavage of tryptophan to N-formylkynurenine within the kynurenine pathway. By modulating intracellular tryptophan availability and generating bioactive kynurenine metabolites, INDOL1 influences immunometabolic signaling, redox balance, and inflammatory gene programs in myeloid and epithelial contexts. Ido2 activity has been studied alongside related tryptophan-catabolic enzymes in mechanisms shaping antigen presentation, tolerance-like responses, and cytokine networks. Dysregulated kynurenine pathway flux and altered tryptophan metabolism are associated with immune dysfunction and inflammation-linked disease models, supporting Ido2 as a useful node for pathway interrogation.
INDOL1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Ido2 expression without altering the underlying DNA sequence.
INDOL1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Ido2 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 Ido2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous INDOL1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Ido2 locus and enabling the study of INDOL1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of INDOL1 pathway restoration in tumor cells with silenced or reduced Ido2 expression.
