CCR5 encodes the chemokine receptor CKR-5, a seven-transmembrane GPCR expressed on subsets of T cells, macrophages, and dendritic cells that binds ligands such as CCL3, CCL4, and CCL5 to direct leukocyte chemotaxis. CKR-5 signaling engages heterotrimeric G proteins and downstream PI3K–AKT, PLCβ–Ca²⁺, and MAPK pathways to regulate migration, adhesion, and inflammatory cytokine programs. Variation in CCR5 expression or function influences immune cell trafficking and has been extensively studied in contexts of mucosal inflammation and immune homeostasis. CCR5 is also a well-established host factor in viral entry biology, making it a common target in mechanistic studies of infection-related cell signaling and receptor regulation.
CKR-5 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CCR5 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CCR5. 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 CCR5 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 CCR5-disrupted clones.
