title: A new view of an old pore.
abstract: Despite reports suggesting a potential role in membrane fusion, the V(0) subunit of the (+)H/ATPase has remained an unlikely candidate for the fusion pore. In this issue of Cell, Hiesinger and coworkers (Hiesinger et al., 2005) present a forward genetic screen that reveals it to be necessary for synaptic vesicle fusion, independent of its role in vesicle acidification.
