Carnitine/acylcarnitine translocase and carnitine palmitoyltransferase 2 form a complex in the inner mitochondrial membrane (vol 394, pg 307, 2014)

Carnitine/acylcarnitine translocase and carnitine palmitoyltransferase 2 are members of the carnitine system, which are responsible of the regulation of the mitochondrial CoA/acyl-CoA ratio and of supplying substrates for the ß-oxidation to mitochondria. This study, using cross-Linking reagent, Blue native electrophoresis and immunoprecipitation followed by detection with immunoblotting, shows conclusive evidence about the interaction between carnitine palmitoyltransferase 2 and carnitine/acylcarnitine translocase supporting the channeling of acylcarnitines and carnitine at level of the inner mitochondrial membrane.
