Map2k1 encodes MEK-1, a dual-specificity kinase that phosphorylates and activates ERK1/2 to propagate signals from RAS and RAF through the canonical MAPK/ERK cascade. This pathway integrates growth factor and cytokine inputs to regulate cell-cycle progression, differentiation, survival, and transcriptional programs via downstream effectors such as ELK1, c-FOS, and MYC. MEK-1 activity is modulated by scaffold and feedback mechanisms that shape signaling amplitude and duration, supporting precise control of developmental and tissue homeostasis processes in mouse models. Dysregulated MAP2K1/MEK-1 signaling is widely implicated in aberrant proliferation and lineage specification, making it a central node for studying oncogenic signaling dynamics, resistance mechanisms, and pathway cross-talk.
MEK-1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Map2k1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Map2k1. 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 Map2k1 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 Map2k1-disrupted clones.
