MAPK7 encodes ERK5, an atypical mitogen-activated protein kinase activated downstream of MEK5 in response to growth factors and cellular stress. ERK5 integrates signaling from the MAPK cascade to regulate transcriptional programs controlling proliferation, survival, differentiation, and cytoskeletal dynamics, with prominent roles in endothelial function and shear-stress signaling. Through phosphorylation of substrates and regulation of transcription factors such as MEF2 family members, ERK5 influences inflammatory signaling and cellular adaptation to microenvironmental cues. Dysregulated MAPK7/ERK5 activity has been associated with altered oncogenic signaling networks and vascular and inflammatory phenotypes, making it a useful node for pathway and mechanism studies in human cells.
ERK 5 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MAPK7 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MAPK7. 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 MAPK7 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 MAPK7-disrupted clones.
