MC1R encodes the melanocortin 1 receptor (MC1-R), a G protein–coupled receptor predominantly expressed in melanocytes that regulates pigmentation and cellular stress responses. Upon binding melanocortin peptides such as α-MSH, MC1-R activates Gs/adenylyl cyclase signaling to elevate cAMP, driving MITF-dependent transcription and shifting melanogenesis toward eumelanin production. This pathway integrates with UV-induced DNA damage responses and redox homeostasis, influencing melanocyte survival and inflammatory signaling in the skin. Genetic variation and altered MC1R activity are associated with pigmentation phenotypes and increased susceptibility to UV-related skin pathology, making it a widely used locus for mechanistic studies in melanocyte biology and photobiology.
MC1-R Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MC1R locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MC1R. 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 MC1R 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 MC1R-disrupted clones.
