ELK1 encodes the ETS-domain transcription factor Elk-1, a nuclear effector of MAPK/ERK signaling that couples extracellular growth factor and stress cues to rapid transcriptional responses. Upon phosphorylation by ERK, JNK, or p38, Elk-1 cooperates with serum response factor at serum response elements to regulate immediate early genes controlling proliferation, differentiation, neuronal plasticity, and apoptosis. Dysregulated ELK1 activity has been associated with oncogenic signaling programs and aberrant inflammatory and neurodegenerative processes, making it a useful node for studying stimulus-dependent transcription and chromatin remodeling. In human cells, Elk-1 also integrates kinase pathway crosstalk with promoter-proximal transcriptional control, supporting mechanistic studies of signal transduction and gene regulatory networks.
Elk-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ELK1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ELK1. 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 ELK1 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 ELK1-disrupted clones.
