Human GAPDH encodes glyceraldehyde-3-phosphate dehydrogenase, a central glycolytic enzyme that catalyzes the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate while generating NADH. Beyond energy metabolism, GAPDH participates in redox homeostasis, RNA binding, membrane trafficking, and stress-responsive signaling, with context-dependent roles in apoptosis and autophagy. Its expression and post-translational regulation track with metabolic reprogramming and hypoxia-responsive pathways, making it relevant to studies of proliferative states, inflammation, and neurodegenerative processes where glycolytic flux and oxidative stress are altered.
GAPDH CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous GAPDH expression without altering the underlying DNA sequence.
GAPDH CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the GAPDH 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 GAPDH transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous GAPDH expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native GAPDH locus and enabling the study of GAPDH-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of GAPDH pathway restoration in tumor cells with silenced or reduced GAPDH expression.
