CPT1C (carnitine palmitoyltransferase 1C) is a brain-specific isoform of the carnitine palmitoyltransferase 1 (CPT1) family, a group of rate-limiting enzymes in fatty acid oxidation. Located on the outer mitochondrial membrane, CPT1 enzymes catalyze the transfer of long-chain fatty acids into mitochondria for β-oxidation. Unlike its liver (CPT1A) and muscle (CPT1B) counterparts, CPT1C is uniquely expressed in neurons and localizes to the endoplasmic reticulum rather than mitochondria, suggesting distinct regulatory roles.
Discovered in the early 2000s, CPT1C gained attention for its involvement in energy homeostasis and neuronal functions. It acts as a metabolic sensor, responding to changes in cellular energy status by interacting with malonyl-CoA, a key intermediate in fatty acid synthesis. Studies link CPT1C to appetite regulation, neuroprotection, and synaptic plasticity. Its ability to bind acyl-CoA derivatives positions it as a potential mediator between lipid metabolism and neuronal signaling pathways.
Recombinant CPT1C protein is produced using heterologous expression systems (e.g., E. coli, mammalian cells) for structural and functional studies. Purified CPT1C enables research into its enzymatic kinetics, substrate specificity, and interactions with regulatory molecules. Emerging evidence implicates CPT1C dysregulation in metabolic disorders, neurodegenerative diseases (e.g., Alzheimer's), and cancer progression, driving interest in its therapeutic potential. Current investigations focus on its non-canonical roles in lipid sensing and stress adaptation beyond classical fatty acid oxidation pathways.
