Carnitine palmitoyltransferase 1A (CPT1A, CPT1-L, or L-CPT1) is an hepatic enzyme that, together with CPT2 and carnitine-acylcarnitine translocase, mediates the oxidation of long chain fatty acids to produce energy, in periods of fasting. CPT1A is localized in the outer mitochondrial membrane and catalyzes the addition of carnitine to long-chain fatty acids thereby enabling effective transport of these molecules to the inner mitochondrial membrane where they are metabolized. CPT1A may function as part of a complex consisting of the acyl-CoA synthetase (ACSL) and the voltage-dependent anion channel (VDAC) and is regulated by malonyl-CoA. Deficiencies in CPT1A result in hypoketotic hypoglycemia.

~78 kDa observed. An uncharacterized band appears at ~32 kDa in some lysates. The calculated molecular weight is 88 kDa, however CPT1A has been shown as a ~78 kDa band in western blots (Tan, L., et al (2011). J Inherit Metab Dis. 34:443–447.)

GST-tagged recombinant protein corresponding to rat CPT1A.
