ARAF encodes the serine/threonine kinase A‑Raf, a RAF family member that links activated RAS to the MAPK/ERK signaling cascade. Through regulated activation and dimerization, A‑Raf contributes to phosphorylation of MEK and downstream control of cell proliferation, differentiation, and survival programs. ARAF activity intersects with growth factor receptor signaling and can influence feedback regulation within the ERK pathway and cross-talk with PI3K–AKT signaling. Dysregulated RAF–MEK–ERK signaling, including altered RAF isoform usage, is broadly relevant to oncogenic signaling networks and to modeling context-dependent pathway dependencies in human cells.
A-Raf Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ARAF locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ARAF. 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 ARAF 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 ARAF-disrupted clones.
