MYOM2 encodes myomesin-2, a major structural component of the sarcomeric M-band that crosslinks thick filaments and stabilizes myofibril architecture in striated muscle. By organizing myosin filament alignment and contributing to passive elasticity, myomesin-2 supports efficient force transmission during contraction and mechanical stress adaptation. MYOM2 expression and M-band integrity are coordinated with sarcomere assembly programs and mechanotransduction processes that shape cardiomyocyte and skeletal muscle function. Altered sarcomeric scaffolding and MYOM2 dysregulation have been associated with inherited cardiomyopathies and myofibrillar defects, making it relevant for studies of muscle disease mechanisms.
myomesin-2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous MYOM2 expression without altering the underlying DNA sequence.
myomesin-2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the MYOM2 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 MYOM2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous myomesin-2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native MYOM2 locus and enabling the study of myomesin-2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of myomesin-2 pathway restoration in tumor cells with silenced or reduced MYOM2 expression.
