title: ATP transport and ABC proteins.
abstract: ATP can be exported into the extracellular space, where it has important biological effects. Recent evidence shows that direct ATP export across the plasma membrane is associated with the presence of ABC proteins. Do the ABC proteins pump ATP as well as their other substrates, and if so, why?
