Tethering molecules in membrane traffic.
Membrane transport in eukaryotic cells proceeds through a variety of organelles. Specificity of a given fusion event between two membranes can be regulated at different levels of docking and fusion. This review summarises recent progress that has been made in understanding the molecular links between the core fusion machinery and upstream regulation.
