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.
