Proteins involved in vesicular transport and membrane fusion

Abstract

In the past year, new information about proteins involved in vesicular transport has been plentiful. Particularly noteworthy are the complementary findings that Sec17p is required for vesicle consumption in endoplasmic reticulum-to-Golgi transport in yeast and that an analogous activity in mammalian cells, termed SNAP, is required for transport from the cis to the medial cisternae of the Golgi apparatus.
