CHRM5 encodes the human muscarinic acetylcholine receptor M5 (mAChR M5), a G protein–coupled receptor that primarily engages Gq/11 signaling to stimulate phospholipase C, inositol trisphosphate/diacylglycerol production, intracellular Ca²⁺ mobilization, and downstream PKC and MAPK pathway activity. Through these cascades, M5 can modulate neuronal excitability, synaptic signaling, and neurovascular responses, while also influencing secretory and smooth muscle processes in a cell-type-dependent manner. CHRM5 expression and cholinergic signaling dynamics are frequently examined in the context of dopaminergic circuit regulation, neuroinflammation, and behavioral phenotypes relevant to substance use and other neuropsychiatric research areas.
mAChR M5 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CHRM5 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CHRM5. 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 CHRM5 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 CHRM5-disrupted clones.
