Mettl3 encodes METTL3, the catalytic core of the mRNA N6-methyladenosine (m6A) writer complex that deposits m6A marks on coding and noncoding RNAs to modulate RNA splicing, nuclear export, translation, and turnover. In mouse cells, METTL3-dependent m6A remodeling integrates with transcriptional programs and RNA surveillance pathways to shape cell fate decisions, stress responses, and lineage specification. Altered METTL3 activity has been linked to dysregulated epitranscriptomic control in developmental phenotypes and disease-relevant contexts, including oncogenic signaling, immune regulation, and neurobiology. As a central epitranscriptomic regulator, METTL3 is frequently studied to connect RNA methylation with pathway-level changes in proliferation, differentiation, and RNA metabolism.
METTL3 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Mettl3 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Mettl3. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt Mettl3 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of Mettl3-disrupted clones.
