SNAT3 CRISPR Activation Plasmid (h) | sc-403696-ACT | 20 µg | $397.00 |
SLC38A3 encodes the sodium-coupled neutral amino acid transporter SNAT3 (system N), a plasma membrane carrier that mediates Na+-dependent transport of glutamine, asparagine, histidine, and related substrates. SNAT3 supports nitrogen shuttling, anaplerosis, and amino acid–dependent signaling by regulating intracellular glutamine availability and exchange across epithelial and parenchymal barriers, including roles described in liver, kidney, and glial metabolic coupling. Through its impact on glutamine flux, SNAT3 intersects with pathways controlling ammonia handling, acid–base homeostasis, and mTORC1-linked nutrient sensing. Dysregulated amino acid transport and altered glutamine metabolism are frequently studied in contexts such as metabolic stress, neurobiology, and tumor cell nutrient adaptation, making SLC38A3 a useful target for mechanistic studies of transporter-mediated rewiring.
SNAT3 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous SLC38A3 expression without altering the underlying DNA sequence.
SNAT3 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the SLC38A3 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 SLC38A3 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous SNAT3 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native SLC38A3 locus and enabling the study of SNAT3-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of SNAT3 pathway restoration in tumor cells with silenced or reduced SLC38A3 expression.
