ARC encodes activity-regulated cytoskeleton-associated protein (Arc), an immediate early gene product that couples neuronal activity to synaptic remodeling. Arc regulates AMPA receptor endocytosis, actin cytoskeleton dynamics, and trafficking of postsynaptic components, thereby shaping long-term potentiation/depression and homeostatic synaptic scaling. Through interactions with endocytic and cytoskeletal machinery, Arc integrates signaling downstream of glutamatergic neurotransmission and calcium-dependent pathways to modulate experience-dependent plasticity. Altered ARC expression or function has been linked to mechanisms implicated in neuropsychiatric and neurodegenerative research, including dysregulated synaptic connectivity and memory-associated processes.
Arc Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ARC locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ARC. 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 ARC 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 ARC-disrupted clones.
