title: Do cytoskeletal components control fatty acid translocation into liver mitochondria?
abstract: For two decades it has been assumed that inhibition of carnitine palmitoyltransferase I (CPT-I) by malonyl-CoA represents the main regulatory mechanism of liver ketogenesis. However, recent evidence indicates that CPT-I activity is also controlled by interactions between mitochondria and cytoskeletal components. This newly recognized mechanism emphasizes the emerging role of the cytoskeleton in the regulation of metabolic pathways.
