| Background Information | Carnitine palmitoyltransferase II (CPT2, or CPT II) belongs to the carnitine/choline acetyltransferase family. It is a ubiquitous protein found in the inner membrane of the mitochondria and plays an essential role in fatty acid β-oxidation. CPT2 is part of the system involving CPT1 and carnitine/acylcarnitine translocase (CACT), that facilitate the transport of long chain fatty acids into the mitochondrial matrix. CPT2 plays the role of restoring these molecules to original esterified forms suitable for β-oxidation, after they arrive in the matrix. Defects in CPT2 has varying outcomes: in adults, it results in episodes of rhabdomyolysis (breakdown of muscle fibers which circulate in the bloodstream), after prolonged and vigorous exercise; and in infants, CPT2 deficiency induces hypoketotic hypoglycemia and eventual cardiac damage. |

| Entrez Gene Number |
|
| Entrez Gene Summary | The protein encoded by this gene is a nuclear protein which is transported to the mitochondrial inner membrane. Together with carnitine palmitoyltransferase I, the encoded protein oxidizes long-chain fatty acids in the mitochondria. Defects in this gene are associated with mitochondrial long-chain fatty-acid (LCFA) oxidation disorders. [provided by RefSeq, Jul 2008]. |

| UniProt Summary | CATALYTIC ACTIVITY: Palmitoyl-CoA + L-carnitine = CoA + L-palmitoylcarnitine. PATHWAY: Lipid metabolism; fatty acid beta-oxidation. SUBCELLULAR LOCATION: Mitochondrion inner membrane; Peripheral membrane protein; Matrix side. INVOLVEMENT IN DISEASE: Defects in CPT2 are the cause of carnitine palmitoyltransferase 2 deficiency late-onset (CPT2D) [MIM:255110]; also known as CPT-II deficiency or CPT2 deficiency. CPT2D is an autosomal recessive disorder characterized by recurrent myoglobinuria, episodes of muscle pain, stiffness, and rhabdomyolysis. These symptoms are triggered by prolonged exercise, fasting or viral infection and patients are usually young adults. In addition to this classical, late-onset, muscular type, a hepatic or hepatocardiomuscular form has been reported in infants. Clinical pictures in these children or neonates include hypoketotic hypoglycemia, liver dysfunction, cardiomyopathy and sudden death. Ref.3 Ref.11 Ref.12 Ref.13 Ref.14 Ref.15 Ref.16 Ref.17 Ref.18 Ref.20 Ref.21 Ref.22 Defects in CPT2 are the cause of carnitine palmitoyltransferase 2 deficiency infantile (CPT2DI) [MIM:600649]. A disorder of mitochondrial long-chain fatty acid oxidation characterized by hepatic or hepato-cardio-muscular manifestations with onset in infancy. Clinical features include hypoketotic hypoglycemia, lethargy, seizures, hepatomegaly, liver dysfunction, cardiomegaly and dilated cardiomyopathy. Defects in CPT2 are the cause of carnitine palmitoyltransferase 2 deficiency lethal neonatal (CPT2D-LN) [MIM:608836]; also known as lethal neonatal CPT-II deficiency. It is a lethal neonatal form of CPT2D. This rarely presentation is antenatal with cerebral periventricular cysts and cystic dysplastic kidneys. The clinical variability of the disease is likely attributed to the variable residual enzymatic activity. Defects in CPT2 are a cause of susceptibility to encephalopathy acute infection-induced type 4 (IIAE4) [MIM:614212]. A severe neurologic complication of an infection. It manifests within days in otherwise healthy children after common viral infections, without evidence of viral infection of the brain or inflammatory cell infiltration. In affected children, high-grade fever is accompanied within 12 to 48 hours by febrile convulsions, often leading to coma, multiple-organ failure, brain edema, and high morbidity and mortality. The infections are usually viral, particularly influenza, although other viruses and even mycoplasma have been found to cause the disorder. Note=Polymorphic variants in CPT2 can confer susceptibility to infection-induced encepalopathy. These variants do not cause classical carnitine palmitoyltransferase 2 deficiency, and patients harboring any of them are asymptomatic most of the time. However, they are prone to viral infection (high fever)-related encephalopathy (Ref.25). Ref.23 Ref.25 SEQUENCE SIMILARITIES: Belongs to the carnitine/choline acetyltransferase family. |
| Molecular Weight | ~68 kDa observed (cleaved form). Uniprot gives a calculated weight of 74 kDa; however, CPT2 has been observed at ~68 kDa. (Faye, A, et Al. (2007). The Journal of Biological Chemistry. 282(37):26908–26916.). Uncharacterized bands appear at ~55, 58, 72, and 100 kDa in some lysates. |
