Nicotinic Acetylcholine Receptor alpha 4/CHRNA4 Double Nickase Plasmid (h2) | sc-401605-NIC-2 | 20 µg | $410.00 |
CHRNA4 encodes the α4 subunit of neuronal nicotinic acetylcholine receptors (nAChRs), which assemble as pentameric ligand-gated cation channels commonly with β2 subunits to form high-affinity α4β2 receptors. Upon acetylcholine or nicotine binding, these receptors mediate Na⁺ and Ca²⁺ influx to regulate membrane excitability, synaptic transmission, and activity-dependent plasticity in cholinergic circuits. CHRNA4-dependent signaling intersects with calcium-dependent pathways and neurotransmitter release programs that shape attention, arousal, and reward-related neuronal network function. Genetic and functional perturbations in CHRNA4 have been associated with neuropsychiatric and neurological phenotypes, making it a relevant target for mechanistic studies of cholinergic signaling and receptor biology.
Nicotinic Acetylcholine Receptor alpha 4/CHRNA4 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CHRNA4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CHRNA4. 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 CHRNA4 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 CHRNA4-disrupted clones.
