MAPK1 encodes ERK2, a core serine/threonine kinase in the canonical RAS–RAF–MEK–ERK MAPK cascade that converts extracellular growth cues into phosphorylation-driven transcriptional programs. ERK2 regulates cell-cycle progression, differentiation, survival, migration, and stress responses through substrates in the cytosol and nucleus, including transcription factors and chromatin-associated regulators. Dysregulated ERK signaling is frequently linked to aberrant proliferative signaling in cancer biology and contributes to inflammatory and neurodegenerative disease mechanisms through altered pathway feedback and cross-talk. As a central signaling node, ERK2 is widely used to interrogate pathway dynamics, feedback control, and context-dependent signaling outputs.
ERK 2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MAPK1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MAPK1. 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 MAPK1 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 MAPK1-disrupted clones.
