CKB encodes creatine kinase-B, a cytosolic phosphotransferase that catalyzes reversible transfer of phosphate between ATP and creatine to buffer cellular energy charge. As a key component of the phosphocreatine shuttle, CKB supports rapid ATP regeneration and couples energy demand to glycolysis and oxidative phosphorylation, particularly in excitable and metabolically active tissues. Creatine kinase-B activity influences processes such as cytoskeletal dynamics, membrane ion transport, and synaptic function through local control of ATP availability. Altered CKB expression or activity has been associated with metabolic stress phenotypes and is frequently investigated in contexts of neurobiology and tumor cell energetics.
creatine kinase-B Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CKB locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CKB. 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 CKB 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 CKB-disrupted clones.
