Carnitine O-palmitoyltransferase 2, mitochondrial is an enzyme that in humans is encoded by the CPT2 gene.^[5]^[6]

Function[]

Carnitine palmitoyltransferase II precursor (CPT2) is a mitochondrial membrane protein which is transported to the mitochondrial inner membrane. CPT2 together with carnitine palmitoyltransferase I oxidizes long-chain fatty acids in the mitochondria. Defects in this gene are associated with mitochondrial long-chain fatty-acid (LCFA) oxidation disorders and carnitine palmitoyltransferase II deficiency.^[6]

Acyl-CoA from cytosol to the mitochondrial matrix

Model organisms[]

Model organisms have been used in the study of CPT2 function. A conditional knockout mouse line called Cpt2^{tm1b(KOMP)Wtsi} was generated at the Wellcome Trust Sanger Institute.^[7] Male and female animals underwent a standardized phenotypic screen^[8] to determine the effects of deletion.^[9]^[10]^[11]^[12] Additional screens performed: - In-depth immunological phenotyping^[13]
