**Background of CPT1A Recombinant Protein**
Carnitine palmitoyltransferase 1A (CPT1A) is a mitochondrial enzyme critical for fatty acid oxidation (FAO), the process by which long-chain fatty acids are transported into mitochondria for energy production. As the rate-limiting enzyme of this pathway, CPT1A catalyzes the transfer of acyl groups from fatty acyl-CoA to carnitine, enabling their transport across the mitochondrial membrane. It is predominantly expressed in the liver, skeletal muscle, and heart, playing a key role in metabolic homeostasis, particularly during fasting or high-energy demand.
CPT1A activity is tightly regulated by malonyl-CoA, a metabolite that inhibits the enzyme during fed states to balance lipid and carbohydrate utilization. Dysregulation of CPT1A is linked to metabolic disorders, including insulin resistance, non-alcoholic fatty liver disease (NAFLD), and type 2 diabetes. Additionally, CPT1A deficiency, a rare autosomal recessive disorder, causes severe hypoketotic hypoglycemia and hepatic encephalopathy due to impaired FAO.
Recombinant CPT1A protein is produced using expression systems (e.g., *E. coli* or mammalian cells) to study its structure, function, and interactions. This engineered protein retains enzymatic activity and is widely used in drug discovery, mechanistic studies, and diagnostic assays. Researchers employ it to investigate CPT1A’s role in metabolic diseases, cancer (where altered FAO supports tumor growth), and potential therapeutic targeting. Its recombinant form also aids in screening small-molecule modulators to correct FAO defects or modulate energy metabolism in pathological conditions.
Overall, CPT1A recombinant protein serves as a vital tool for unraveling metabolic pathways and developing treatments for disorders linked to mitochondrial lipid metabolism.
