Human MDN1 encodes Midasin, a large AAA+ ATPase that is essential for late-stage 60S ribosomal subunit biogenesis. Midasin uses ATP-driven remodeling to coordinate release of assembly factors and quality control during nucleolar and nucleoplasmic maturation, linking ribosome production to cell-cycle progression and proteostasis. Through its role in ribosome assembly, MDN1 influences global translational capacity and cellular stress responses, including nucleolar stress signaling. Perturbation of ribosome biogenesis pathways involving MDN1 is relevant to mechanistic studies of growth control and disorders associated with defective ribosomal assembly.
Midasin CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous MDN1 expression without altering the underlying DNA sequence.
Midasin CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the MDN1 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 MDN1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Midasin expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native MDN1 locus and enabling the study of Midasin-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Midasin pathway restoration in tumor cells with silenced or reduced MDN1 expression.
