MAN1 CRISPR Activation Plasmid (h) | sc-404258-ACT | 20 µg | $397.00 |
Human LEMD3 encodes the inner nuclear membrane protein MAN1, a LEM-domain factor that links nuclear architecture to transcriptional control. MAN1 binds receptor-regulated SMADs and modulates TGF-β/BMP signaling output, influencing programs that govern extracellular matrix regulation, differentiation, and tissue homeostasis. Through interactions with lamins and chromatin-associated complexes, MAN1 contributes to nuclear envelope organization and mechanoresponsive gene regulation. Dysregulation of LEMD3/MAN1 activity has been associated with connective tissue and skeletal phenotypes and is studied in contexts where altered SMAD-dependent transcription and nuclear envelope function converge.
MAN1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous LEMD3 expression without altering the underlying DNA sequence.
MAN1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the LEMD3 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 LEMD3 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous MAN1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native LEMD3 locus and enabling the study of MAN1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of MAN1 pathway restoration in tumor cells with silenced or reduced LEMD3 expression.
