DNAH3 CRISPR Activation Plasmid (h) | sc-410012-ACT | 20 µg | $397.00 |
DNAH3 encodes dynein axonemal heavy chain 3, a microtubule-based ATPase that contributes to the motility and structural integrity of axonemal cilia and flagella. As part of the dynein arm machinery, DNAH3 supports ciliary beat generation and coordination within the cilium/axoneme pathway, influencing fluid flow and mechanosensory signaling in ciliated tissues. Perturbation of axonemal dynein components is broadly associated with ciliopathy-related phenotypes, including laterality defects and male infertility, and altered ciliary function can intersect with developmental signaling programs such as Hedgehog. These features make DNAH3 a useful target for dissecting cilia-driven processes, cytoskeletal dynamics, and genotype–phenotype relationships in human cell models.
DNAH3 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous DNAH3 expression without altering the underlying DNA sequence.
DNAH3 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the DNAH3 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 DNAH3 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous DNAH3 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native DNAH3 locus and enabling the study of DNAH3-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of DNAH3 pathway restoration in tumor cells with silenced or reduced DNAH3 expression.
