Human DYNLT1 encodes Tctex1, a dynein light chain that assembles with cytoplasmic dynein to support microtubule-based transport, organelle positioning, and intracellular trafficking. Through interactions within the dynein–dynactin motor complex, Tctex1 contributes to processes such as mitotic spindle organization, centrosome function, and cargo movement that shape cell polarity and division. DYNLT1-dependent transport has been linked to neuronal and ciliary biology via regulation of protein localization and signaling compartmentalization. Dysregulation of dynein-associated transport pathways is frequently studied in the context of neurodegenerative mechanisms and altered proliferative states, making DYNLT1 a useful node for investigating cytoskeletal dynamics and signaling outcomes.
Tctex1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous DYNLT1 expression without altering the underlying DNA sequence.
Tctex1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the DYNLT1 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 DYNLT1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Tctex1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native DYNLT1 locus and enabling the study of Tctex1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Tctex1 pathway restoration in tumor cells with silenced or reduced DYNLT1 expression.
