FRONT COVER
===========

1. Schematic diagram of a eukaryotic cell showing various intracellular
   organelles in which proteins are trafficked and the route of protein
   secretion outside (arrows).
2. Representation of the signal hypothesis. Proteins trafficking to 
   different organelles are shown in brown and the signal sequences are 
   indicated in red.
3. A model showing early events in the entry of secretory proteins in the 
   endoplasmic reticulum. The protein-conducting channel discovered by 
   Blobel is labeled as membrane channel.
