METTL3 encodes the catalytic core of the mRNA N6-methyladenosine (m6A) methyltransferase complex, partnering with METTL14 and cofactors such as WTAP to install m6A marks on coding and noncoding RNAs. This RNA modification influences transcript stability, splicing, nuclear export, and translation, thereby shaping programs linked to cell-cycle control, differentiation, stress responses, and innate immune signaling. METTL3-dependent m6A regulation intersects with RNA metabolism pathways and epitranscriptomic control of gene expression, including modulation of signaling outputs such as MAPK, PI3K–AKT, and DNA damage response networks through altered mRNA fate. Dysregulated METTL3 activity has been associated with diverse disease-relevant phenotypes in cancer biology, hematopoiesis, and inflammatory contexts, making it a frequent target in mechanistic studies of RNA-based regulation.
METTL3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the METTL3 locus in human 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.
