CPT1B encodes carnitine palmitoyltransferase 1B (CPTI-M), the muscle-associated outer mitochondrial membrane enzyme that catalyzes the rate-limiting formation of long-chain acylcarnitines for import into mitochondria and subsequent β-oxidation. By controlling fatty acid entry into the mitochondrial matrix, CPTI-M helps regulate lipid catabolism, energy homeostasis, and substrate switching between fatty acids and glucose, integrating with AMPK signaling, PPAR-driven metabolic transcription programs, and malonyl-CoA–mediated control of fatty acid flux. Altered CPT1B activity or expression has been linked to dysregulated fatty acid oxidation, lipotoxic stress, and metabolic remodeling that is relevant to cardiometabolic phenotypes and muscle energetics. In research settings, CPT1B is commonly examined in the context of mitochondrial function, acylcarnitine profiling, oxidative capacity, and metabolic adaptation to nutrient availability.
CPTI-M Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CPT1B locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CPT1B. 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 CPT1B 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 CPT1B-disrupted clones.
