CB1/Cannabinoid Receptor 1/CNR1 Double Nickase Plasmid (h2) | sc-400648-NIC-2 | 20 µg | $410.00 |
CNR1 encodes cannabinoid receptor 1 (CB1), a Gi/o-coupled GPCR that responds to endocannabinoids to regulate adenylyl cyclase activity, cAMP/PKA signaling, ion channel conductance, and downstream MAPK/ERK and PI3K-related pathways. CB1 is broadly expressed in the nervous system and contributes to synaptic transmission, neurotransmitter release, and activity-dependent plasticity, with additional roles in peripheral metabolic and immune-related processes. Altered CNR1/CB1 signaling has been associated with neuropsychiatric and neurodegenerative phenotypes, pain processing, and metabolic dysregulation, making it a commonly studied node in GPCR pharmacology and neuromodulatory circuitry. In cell models, CNR1 perturbation is used to interrogate receptor desensitization/internalization, G-protein coupling bias, and pathway cross-talk affecting neuronal excitability and inflammatory signaling.
CB1/Cannabinoid Receptor 1/CNR1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CNR1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CNR1. 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 CNR1 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 CNR1-disrupted clones.
