β¦ Synopsis
The cellular machinery responsible for conveying proteins between the endoplasmic reticulum and the Golgi is being investigated using genetics and biochemistry. A role for vesicles in mediating protein traffic between the ER and the Golgi has been established by characterizing yeast mutants defective in this process, and by using recently developed cell-free assays that measure ER to Golgi transport. These tools have also allowed the identification of several proteins crucial to intracellular protein trafficking. The characterization and possible functions of several GTP-binding proteins, peripheral membrane proteins, and an integral membrane protein during ER to Golgi transport are discussed here.

Several complementary approaches have been fruitful in the study of transport from the ER to the Golgi complex in yeast. Mutational analysis has led to the identification of genes required for this process, many of which are now being studied at the molecular and biochemical level. In the case of SE
Previous studies have shown that gradual progressive hypoxia specifically inhibits the synthesis of the major myelin lipid galactosylceramide (GalCer) in cultured neonatal rat oligodendrocytes (OLG) (Kendler and Dawson, J Biol Chem 26512259-12266, 1990). The inhibition of de novo synthesized GalCer
## Abstract Uso1 is a yeast essential protein that functions to tether vesicles in the ERβtoβGolgi transport. Its recruitment to the ERβderived vesicles has been demonstrated in in vitro membrane transport systems using semiβintact cells. Here we report that the binding of Uso1 to specific membrane
