α-taxilin CRISPR Activation Plasmid (h) | sc-404316-ACT | 20 µg | $397.00 |
Human TXLNA encodes α-taxilin, a cytosolic protein that associates with syntaxins and other components of the SNARE machinery to support vesicle trafficking and regulated exocytosis. Through its interactions with membrane fusion factors, α-taxilin contributes to intracellular transport processes that influence secretion, membrane protein delivery, and signaling dynamics. Altered expression of TXLNA has been reported in multiple pathological contexts, motivating studies of how vesicular transport and SNARE-linked pathways intersect with cellular stress responses and growth control. These features make TXLNA a useful target for investigating trafficking-dependent regulation of cell state and disease-relevant phenotypes.
α-taxilin CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous TXLNA expression without altering the underlying DNA sequence.
α-taxilin CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the TXLNA 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 TXLNA transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous α-taxilin expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native TXLNA locus and enabling the study of α-taxilin-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of α-taxilin pathway restoration in tumor cells with silenced or reduced TXLNA expression.
