Map2k5 encodes the dual-specificity kinase MEK-5, a MAPK kinase that preferentially activates ERK5/MAPK7 within the MAPK signaling network. MEK-5–ERK5 signaling regulates stimulus-dependent transcription, cytoskeletal organization, and cell survival programs, with established roles in responses to growth factors and cellular stress. In mouse systems, this pathway is widely used to interrogate mechanisms of proliferation and differentiation in multiple tissue contexts. Dysregulation of MEK-5/ERK5 signaling has been associated with altered inflammatory signaling and oncogenic phenotypes, supporting its relevance for modeling pathway-dependent disease biology.
MEK-5 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Map2k5 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Map2k5. 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 Map2k5 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 Map2k5-disrupted clones.
