MC3R encodes the melanocortin-3 receptor (MC3-R), a G protein–coupled receptor primarily activated by melanocortin peptides such as α-MSH. MC3-R couples mainly to Gs to stimulate adenylyl cyclase and cAMP/PKA signaling, integrating neuroendocrine cues that regulate energy homeostasis, nutrient partitioning, and feeding-related behaviors. In metabolic tissues and the central nervous system, MC3-R signaling intersects with hypothalamic circuits controlling appetite and circadian-linked energy balance. Genetic and functional perturbations of MC3R have been associated with obesity-related phenotypes and altered metabolic regulation, making it a relevant target for mechanistic studies in metabolism and neurobiology.
MC3-R Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MC3R locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MC3R. 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 MC3R 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 MC3R-disrupted clones.
