SPNS2 CRISPR Activation Plasmid (h) | sc-405481-ACT | 20 µg | $397.00 |
SPNS2 (spinster homolog 2) encodes a multipass membrane transporter that regulates extracellular sphingosine-1-phosphate (S1P) availability, shaping S1P gradients that coordinate cell migration, vascular and lymphatic homeostasis, and immune cell trafficking. By controlling S1P export, SPNS2 influences GPCR-mediated S1P receptor signaling and downstream pathways including PI3K/AKT, MAPK, and Rho-family GTPase circuits involved in barrier function and cytoskeletal remodeling. Altered SPNS2 activity has been linked to dysregulated inflammatory responses and endothelial/lymphatic phenotypes in experimental systems, making it relevant to studies of immune regulation and vascular biology. As a node in sphingolipid metabolism and signaling, SPNS2 is frequently investigated for its impact on tissue microenvironmental cues and intercellular communication.
SPNS2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous SPNS2 expression without altering the underlying DNA sequence.
SPNS2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the SPNS2 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 SPNS2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous SPNS2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native SPNS2 locus and enabling the study of SPNS2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of SPNS2 pathway restoration in tumor cells with silenced or reduced SPNS2 expression.
