The Menkes disease ATPase (MNK) is a copper transporter that localizes to the mammalian trans-Golgi network (TGN) and shows substantial co-localization wih a ubiquitous TGN resident protein and marker, TGN46. We tested our hypothesis that these two TGN residents and integral membrane proteins are localized to biochemically distinct TGN sub-compartments using constitutively active mutant proteins and drugs that disrupt membrane traffic, lumenal pH and the cellular cytoskeleton. The pH-disrupti...Expand abstract
