Protein sorting in the endomembrane system of plant cells.

Although many properties of the targeting of plant endomembrane proteins are similar to mammalian and yeast systems, several clear differences are found that will be stressed in this review. In the past year, significant advances in our understanding of storage protein segregation in the endoplasmic reticulum, compartmentation of Golgi, and the signals for vacuolar protein targeting have been made. This work will form the basis for determining the mechanism of these sorting phenomena.
