TUBA3C encodes human α3C tubulin, a core α-tubulin isotype that polymerizes with β-tubulin to form microtubules essential for cytoskeletal organization, mitotic spindle assembly, and intracellular transport. Microtubule dynamics coordinate cell cycle progression, centrosome function, and polarized trafficking, influencing processes such as neurite outgrowth and cell migration. Perturbations in tubulin expression or microtubule homeostasis are linked to chromosomal instability and altered sensitivity to microtubule-targeting agents, making tubulin isotypes relevant in studies of proliferative and neurobiological phenotypes. As a structural component of the tubulin pool, α3C tubulin provides a tractable node for dissecting cytoskeleton-dependent signaling and stress responses.
α3C Tubulin CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous TUBA3C expression without altering the underlying DNA sequence.
α3C Tubulin CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the TUBA3C 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 TUBA3C transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous α3C Tubulin expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native TUBA3C locus and enabling the study of α3C Tubulin-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of α3C Tubulin pathway restoration in tumor cells with silenced or reduced TUBA3C expression.
