Carnitine O-palmitoyltransferase 2, mitochondrial is an enzyme that in humans is encoded by the CPT2 gene.[1][2]


Carnitine palmitoyltransferase II precursor (CPT2) is a nuclear 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.[2]

Model organisms[edit]

Model organisms have been used in the study of CPT2 function. A conditional knockout mouse line called Cpt2tm1b(KOMP)Wtsi was generated at the Wellcome Trust Sanger Institute.[3] Male and female animals underwent a standardized phenotypic screen[4] to determine the effects of deletion.[5][6][7][8] Additional screens performed: - In-depth immunological phenotyping[9]
